    The phenomenon of copolymer interaction has become the focus of basic research and applied in-depth research on polyelectrolyte complexes (PECS). Polyelectrolyte complexes made from natural polymers such as proteins and polysaccharides have the added advantage of being non-toxic, bioresorbable. The interaction of protein-based polyelectrolytes has received extensive attention in biotechnology and biomedical sensor applications, such as protein purification, enzyme immobilization, enzyme-linked immunosensing, and bioactivity sensors.

    Some globular proteins and polyelectrolytes (native or synthetic) have been matched and combined for use in various techniques and research objects. Table 1 presents some examples of studies of the structure of protein polysaccharide systems in the literature.

    chemical functional group linking of functional polymer macromolecules; They have potential advantages for small molecules with the same functional group. Its utility is two related functional groups and properties of the polymer, the characteristic properties of which are mainly determined by its super-large molecules.

    Polymers of this functional group are usually the first step in preparing functional polymers for specific uses. However, choosing the right polymer is an important factor in the successful application. In addition to the synthesis of aliphatic and aromatic polymers, a wide range of natural polymers are also used as functional and reactive materials.

    Inorganic polymers are also modified with active functional groups and require severe service conditions during use. In principle, part of the reaction group may be a polymer backbone or attached to the side chain as a pendant group, either directly or through a spacer group. The required active functional groups can be introduced into the polymer support chain (1) that are incorporated into the synthetic support itself through polymerization and copolymerization of momonmers containing the desired functional groups, (2) chemical modification of the function of the support matrix and (3) in combination (1) and (2).

    Each method has its own advantages and disadvantages, and one method may be preferred for the preparation of specific functional polymers while others are completely impractical. The choice between the two countries for the synthesis of functional polymers depends mainly on the thorough examination of the chemical and physical properties required to make full use of the various preparation technologies.

    Rapid progress in utikization of functional polymer materials has been noted in the recent past. Interest in this area is growing, thanks to the possibility of creating systems that combine unuique properties of conventional active groups of polymers. Successfully exploit these polymers based on the physical form of solvation behavior, porosity, chemical reactivity and stability of polymers.

    Various types of functionalized polymers cover a wide range of chemical applications, including polymer reactants, catalysts, carriers, surfactants, stabiliz-ers, ion exchange resins, and other various biological and biomedical fields, such as pharmaceutical, agricultural, food and other industries, where they have become indispensable materials, especially controlled-release preparations for pharmaceuticals and agrochemicals. In addition, these polymers are currently widely used in antioxidants, flame retardants, corrosion inhibitors, coagulants, antistatic agents, and other technical applications. In addition, functional polymers have a broad application prospect, and I hope to adopt them.

    The intrinsic reaction of free radicals.

    For a while, it was believed that one could assess the free radical response and reverse order for monomers by considering changes in the following procedures in stabilizing energy sources

    According to this view, the most active monomers will produce the least aggressive reactions, and so on, because of their structural relationships. To some extent, the data supporting this view suggest that generally vinyl acetate monomer is at least one of the most productive reactions of free radicals, and the opposite is exactly the case with a pair of styrene reactions. Unfortunately, the case of intermediate active substances is far from being so significantly reduced, and it is here that one is forced to conclude that different factors in the decision prove the predominance of different reactive activity.

    The authors give a decisive demonstration of the concept of failure response to the only order examined by examining the polar relative response spectrum of polystyrene (sec) and polyacrylonitrile (ampimetry) radicals across various substrates. The data in the table shows that judging by the ferric chloride transport standard, the S. radical is the same as the free radical is a 5,000 as long as the second is twice the work 100 times. In fact, one can make almost all reactivity noticeable by choosing the right substrate than a radical reaction than others that is considered meaningless baldness.

    Introduction The alkali metal salts of polyacrylic acid are water-soluble, and multifunctional polymer electrolytes with a variety of solubility properties are the active ingredients of various cleaning agents. These polyacrylates contain 10 4000 molecules with the formula -CHZ'CH(COO)- The structural unit of the company.

    Sodium polyacrylate has been used as a thickener and reinforcing agent for synthetic detergents as early as 1949. Around the same time, Edelson and Fuoss used sodium polyacrylate as a template compound in their basic research on the fundamental distinction between polymer electrolytes and simple electrolytes such as sodium bromide.

    However, a recently published patent literature review makes it clear that it was more than two decades before sodium polyacrylate was used on a large scale in the commercial production of synthetic detergents.

    Although polyacrylates are increasingly used in commercial and academic research, there is little literature on the role of polyacrylates in improving the performance of synthetic detergents.

    This article provides a series of studies to determine the multifaceted properties of these special detergent additives under simulated washing conditions, as well as the possible role of polyacrylates in the washing mechanism.

    Experimental Procedure. Experimental materials.

    The polyacrylic acid** used in the study was used in a commercial material (provided by Goodrich Chemicals) and the properties of the polyacrylic acid are shown in Table 1. Sodium polyacrylate is prepared by the neutralization reaction of polyacrylic acid and sodium hydroxide, and the reaction product of pH is collected, and the product is not further purified.

    The polyacrylate concentrate used in this report is attached to a dry polymer matrix. Specific information on other materials and reactants will be given in a later protocol.

    I don't know how it goes, just take a look

    IntroductionThe alkali metal salt of polyacrylic acid is a water-soluble, multi-functional polymer polymer electrolyte, which is a component of laundry detergent and detergent.

    These acrylates contain 10 4000 -chz with a repeating unit structure'ch(coo)-ps: z here'It's weird.,It's supposed to be a foot mark 2 )

    Historically, the earliest mention of sodium acrylate as a thickener for synthetic detergents was in 1949. Around the same time, Edelson and Fuoss, in their basic research, used sodium acrylate as a model compound to illustrate the fundamental differences between such polymeric polymer electrolytes and simple electrolytes such as sodium bromide.

    However, the commercial large-scale use of sodium acrylate as an ingredient in detergents did not work until about 20 years later, as is evident in a recently published review of patent literature.

    While the use of polyacrylates as commercial and experimental detergents has been on the rise, the diversity of functional benefits of a compound detergent based on the end-use performance of a compound detergent in the published literature shows that the benefits are negligible at best.

    This article presents a number of experimental studies aimed at confirming the multifunctional benefits of these specialized detergent additives in a simulated detergent use environment, and the possible role of polyacrylates in the basic washing mechanism.

    The polyacrylic acid used in this experimental study is derived from a commercial material (BF Daifuku Chemical) and its analytical properties are shown in Table 1. By neutralizing with sodium hydroxide, the pH is adjusted to such an extent that it can be converted into sodium salt, and no subsequent purification is required when used. This report gives the concentration of solid polyacrylate.

    Detailed information about other substances and reagents will be listed in due course during the experiments described below.
