Is a class of molecules with high molecular weight aggregation of compounds, also known as macromolecules, macromolecules, etc. Generally relative molecular mass higher than 10000 molecules called polymers. Polymers usually from 103 to 105 Atoms are covalently bonded together.As the polymer is mostly by the small molecules through the polymerization reaction, and therefore often referred to as polymer or polymer, for the polymerization of small molecules are known as "single body".
Definition: A mixture of thousands of atoms covalently bonded to each other to form a compound with a relatively large molecular mass and having a repeating structural unit (which can be divided into an inorganic polymer compound and an organic high molecular compound)
Polymers, also known as macromolecular compounds, refer to compounds with a relative molecular weight of more than 10,000, in which a plurality of atoms or radicals are predominantly covalently bonded.
