What are the differences between polymer compounds and polymers? Is there a affiliation?

It must be said that the number of words is different, and the strokes are not the same. Polymer compounds are polymers. According to IUPAC 1996: Excerpt from Pure Appl ,68, 2287 - 2311

Polymers, also called polymer molecules or macromolecules, have a high relative molecular weight, and their structure consists of multiple repeating units, from which these repeating units are actually or conceptually derived from the corresponding small molecules.

IUPAC is the International Union of Theoretical (Chemical) and Applied Chemistry).

Plastic bag.

Polymers, that is, macromolecules, generally have a molecular weight of more than 10,000.

Polymers, polymer compounds formed by the aggregation of small molecule compounds. For example, polyethylene and polymer formed by the polymerization of small molecule ethylene are often used as plastic bags and agricultural mulch films. For example, polytetrafluoroethylene, which is produced by the polymerization of small molecule tetrafluoroethylene, is often used as a non-stick pan.

In animals and plants, small molecules of glucose polymerize to produce high molecular starch, cellulose, blood sugar, etc. Polymer compound proteins produced by the polymerization of small amino acids.

Polymers can be classified from different perspectives, such as from, heating behavior, polymer structure, etc.

According to the elemental structure of the molecular backbone, polymers can be divided into three categories: carbon chain, heterochain and elemental organic.

The carbon chain polymer macromolecular backbone is composed entirely of carbon atoms. The vast majority of olene and diene polymers belong to this category, such as polyethylene, polystyrene, polyvinyl chloride, etc.

In addition to carbon atoms, there are heteroatoms such as oxygen, nitrogen, and sulfur in the backbone of heterochain polymer macromolecules. Such as polyether, polyester, polyamide, polyurethane, polysulfide rubber, etc. Engineering plastics, synthetic fibers, and heat-resistant polymers are mostly heteropolymers.

There are no carbon atoms in the macromolecular backbone of elemental organic polymers, which are mainly composed of silicon, boron, aluminum, and atoms such as oxygen, nitrogen, sulfur, phosphorus, etc., but the side groups are composed of organic groups, such as methyl, ethyl, vinyl, etc. Silicone rubber is a prime example.

Elemental organic, also known as heterochain, is a semi-organic polymer that becomes an inorganic polymer if there are no carbon atoms in the main chain and side groups.

All substances in the world are composed of molecules, and the number of molecules that make up substances varies greatly. The molecular weight of general substances is mostly only tens to hundreds, and rarely thousands. The molecular weight of silk, hemp, plastics, etc. can be as high as tens of thousands, hundreds of thousands, or even millions.

Therefore, people call this class of substances with high molecular weight "polymer materials", or "polymers".

The molecules in polymer materials are macromolecules that are connected in a certain way, much like a long chain, so they are also called "molecular chains". Because the molecular chains are like rattans that are wound around each other and cling to each other, the result is that the molecules are very tightly combined, which is difficult to separate them and not easy to break.

Refers to a compound with a high molecular weight (degree of polymerization of 100 million) that is formed by repeated links of many identical and simple structural units through covalent bonds. For example, the polyvinyl chloride molecule is made up of a number of vinyl chloride molecular building blocks – CH2CHCL – that are repeatedly linked.

Polymers refer to polymer compounds formed by regular repeated polymerization of simple monomers, such as polyethylene, which is polymerized from repeated ethylene monomers; There are also some polymers with multiple monomers. In summary, a polymer is a fixed repeating unit, which can be composed of a single monomer or multiple monomers.

Polymer compounds only refer to molecules with large molecular weights, and do not necessarily need to have duplicate units, polymers are only one of them, and many others do not contain repeat monomers, such as DNA, proteins, etc.

Polymers, polymers, polymers, refer to the same compound, there is no difference.

Polymers are also known as polymers, polymers.

As an important material, polymer materials have played a huge role in various industrial fields after about half a century of development. The polymer materials industry should not only continue to provide many new products and new materials with a large amount and a wide range of new products and new materials for people's clothing, food, housing and transportation, but also provide more and more effective high-performance structural materials and functional materials for the development of high technology.

There are too many to count. The main ones are:

Polyolene: polyethylene, polypropylene, polystyrene, polyvinyl chloride surplus, etc.

Polyesters: polycarbacytes, terephthalates, etc.

There are also polyamides, polyethers and so on.

Macromolecules of organic compounds.

Polymer compounds are long chains or branched chains formed by chemical reactions of several monomer molecules. These monomeric molecules are linked together by covalent bonds in the reaction to form a high-muffling finch molecular structure. Polymer compounds can exist in nature, such as DNA, proteins, etc.; It can also be obtained through artificial synthesis, such as plastic, rubber, etc.

High pin molecular compounds have a variety of properties, such as high strength, good stability, electrical conductivity, etc. Therefore, it has a wide range of applications in many fields, such as materials science, medicine, cosmetics, etc.

There is no difference between polymers and polymers.

Polymers generally refer to polymer compounds, aliases: polymers, macromolecules. Generally refers to compounds with a relative molecular mass of several thousand to millions, and the vast majority of polymer compounds are mixtures of many homologues with different relative molecular weights, so the relative molecular weight of polymer compounds is the average relative molecular weight.

Polymer compounds are made up of thousands of atoms linked to each other by covalent bonds, and although their relative molecular masses are large, they are all connected in simple structural units and in a repetitive manner.
