Polylene glycol
產(chǎn)品概述
Polylene glycol (PEG) is a polymer made of ethylene glycol molecules connected by a chemical reaction. It has a linear structure, in which the ethylene glycol unit (C2H4O) is repeatedly linked together to form a long chain. The properties of polyethylene glycol can be adjusted by controlling the molecular weight (the degree of polymerization, also known as the length of the polymer), to obtain different chemical and physical properties.
