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.

linkage of chemical functional groups of functional polymer macromolecules; Their potentially dominant small molecules have the same functional set. Their usefulness is related to the functional groups and properties of polymer properties mainly depend on very large size molecules.
Attaching to a polymer functional group is usually the first step in preparing the material for use in a specific functional polymer. However, choosing the right aggregation is an important factor in the successful application. In addition to the synthesis of aliphatic and aromatic polymers, a wide range of natural polymer compounds have also been functionalized and can be used as reactive materials.
Inorganic polymers are also modified to carry hosiery functional groups with active hosiery and the use process is required in harsh environments. In principle, the positive group may be part of the polymer backbone or connect a side chain pendant group as a group that can be requested directly, or by spacer spacer group. A company that needs to introduce active functional groups that can be supported into the polymer chain (L) synthesis process supports itself through the polymerization of comonomers or the inclusion of desired functional groups, taking advantage of the rapid advances that have been noted in functional polymer materials in the recent past.
The enhancement of the field of interest due to the possibility of creating a system that combines the unique properties of traditional active polymers with high molecular weight polymers. Successful utilization of these polymers is based on the behavior, porosity, chemical activity, and stability of the polymer in solid form. Various types of functionalized polymers cover a wide range of chemistries, including polymer reaction material ratios, catalysts, carriers, surfactants, cherry residual stabilizers, ion exchange resins, etc.
They have become indispensable materials in various biological and biomedical fields, such as medicine, agriculture, the food industry and similar investments, especially controlled-release drugs and agrochemical formulations. In addition, these polymers are used as antioxidants in a wide range of applications as flame retardants, corrosion inhibitors, flocculants, antistatic agents, and other technologies. In additioni, functional polymer materials have broad application prospects in high-tech fields, such as conductive materialsi, photosensitizersi, detectorsi, liquid nucleus, tracers, crystalsi, solar energy, storage and conversion of working substances, etc.

1 All ST generally refers to styrene.
The meaning of this sentence:
Styrene itself is a good solvent for polystyrene, and the chain diffusion of polymers is very easy, so the phenomenon of automatic acceleration appears much later than others.
I think there is a slight error in this sentence, the solute here should be solventSolute is solute, solvent is solvent.
The phenomenon of automatic acceleration is generally caused by an increase in the viscosity of the system as the free radical reaction progresses to the middle stage of polymer formation.
The increase in viscosity directly leads to the inhibition of the termination rate of chain radicals.
There is a constant acceleration of aggregation.
The existence of this phenomenon is harmful, often affecting the quality of the product, and the occurrence of explosion will also lead to the danger of local heat accumulation.
Generally, if the monomer is a good solvent for polymers.
The viscosity of the system does not increase significantly after polymer conversion.
It will delay the automatic acceleration of free radical polymerization.
If the conversion rate can be controlled, it can even be achieved without automatic acceleration if the monomer is not a good solvent for polymers.
It can be polymerized in a solution system of a good solvent of the polymer, and when the above methods cannot be established, a chain transfer agent can be added to the system.

Styrene is an effective solvent for polystyrene, and the polymer chain expands very easily in it, so the self-acceleration phenomenon occurs later than in other polymers.

Functional group - Functional groups are atoms and clusters of atoms that determine the chemical properties of organic compounds. It is also known as functional group and functional group. The difference between a functional group and an atomic cluster is that the former is uncharged and cannot exist stably, whereas the latter is charged and can exist stably.
Pendant substituents are also known as side substituents.
Addition polymers do not contain these functional groups as part of their polymer chains. However, these functional groups may be suspended on the outside of the polymer chain as side substituents.

Before the polymer material is processed, it is synthesized to synthesize the monomer into a polymer for granulation, and then it is melt processed. The synthesis methods of polymer materials include bulk polymerization, suspension polymerization, emulsion polymerization, solution polymerization and gas phase polymerization. Among them, initiators play a very important role, azo initiators and peroxide initiators are commonly used initiators, and polymer material additives often play an obvious role in improving the performance of polymer materials and reducing costs. >>>More

This problem is too big, polymer materials are mainly divided into plastics, rubber, coatings, fibers, adhesives, and special polymers. Employment is mainly in these aspects. Take a look at my previous analysis of direction.
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. >>>More
