POLY(ETHYLENE GLYCOL) METHYL ETHER ACRYLATE CAS 32171-39-4

Polyethylene glycol monomethyl ether acrylate, a white to off-white solid at room temperature and pressure, is a functionalized glycol polymer, which is widely used in medical research for its good compatibility with living organisms. The compound is a compound of polyethylene glycol (PEG) with a methyl group (CH3) attached to one end group and a methacryloyl group (CH2=C(CH3)COO) attached to the other end group, and it is a biocompatible homopolymer with a brush-type structure, which is a nonlinear analog of polyethylene glycol (PEG) and is mainly used to provide a modified surface for PEG. As the substance contains multiple oxygen atoms in its structure, it can effectively correlate with water molecules, and it has good solubility in water. The methacryloyl group in polyethylene glycol monomethyl ether acrylate has high reactivity, and it can be used as a reactive group to participate in copolymerization, cross-linking reaction, modification of surfaces and so on in chemical reactions.
