聚乙二醇不饱和酸酯是一类重要的高聚物单体,其与其他单体接枝共聚也可合成多功能化的高分子聚合物.主要综述了聚乙二醇与丙烯酸、甲基丙烯酸、马来酸等共轭烯酸缩合反应的研究进展,并对其发展进行了展望.
Unsaturated acid esters of polyethylene glycol (PEG) are important monomers for the preparation of polymers. In addition, multifunctional polymers can be synthesized by the graft copolymerization of unsaturated acid esters of PEG with other monomers. The research development of the condensation reaction of PEG with conjugated olefine acids, such as acrylic acid, methyl acrylic acid, maleic acid, etc. is reviewed, and its outlook in the future is given.
