PolymersPolymers are compounds with large molecular weights composed of one or several simple low-molecular compounds through polymerization, also known as polymers or macromolecules. The number of atoms contained in the molecules of polymer compounds can reach tens of thousands, or even hundreds of thousands, while the number of atoms of low-molecular compounds is only a few, at most hundreds. It is customary to call those with a molecular weight less than 500 as low-molecular compounds and those with a molecular weight greater than 5000 as high-molecular compounds.
Although the molecular weight of polymers is large, its chemical composition is relatively simple, and it is usually composed of elements such as C, H, O, N, and S.
