Basic concepts of polymers.
The nomenclature of polymers.
Classification of Carbon-and heterogeneous polymers.
The phrase Polymer has many parts. These parts consist of a group of atoms connected to a chemical bond. Plastic sulfur is a polymer whose parts consist of individual atoms. It is formed when molten sulfur is spilled into cold water.

Полимер сөзінің сөзбе-сөз аудармасы көп бөліктер. Бұл бөліктер химиялық байланыспен қосылған атомдардың тобынан тұрады. Бөліктері жеке атомдардан тұратын полимерге пластикалық күкірт жатады. Ол күкірт балқымасын суық суға құйғанда түзіледі.

The properties of plastic sulfur differ from crystalline sulfur-it is a substance formed in the form of rubber, that is, soft, flexible, colorless, and does not have a constant melting point. The melting point of different samples of this substance will differ. Polymer sulfur is unstable and turns into crystalline sulfur within a few days at room temperature. For many polymers, a unit of repeating structure refers to a group of atoms bound in a particular order. The link of polyethylene-the main representative of simple polymers is formed during polymerization of ethylene.
