WebPlastics always consist of large molecules called polymers. Polymers, in turn, consist of many identical small particles that are strung together like a chain. We call these individual small particles monomers. The length of these polymer chains determines the properties of plastic. For example, the length of the polymer chain for polyethylene ...
