【摘要】 聚1,2-丙二醇(PPG)与甲苯二异氰酸酯反应得到端异氰酸酯基聚丙二醇,再与丙烯酸2-羟基乙酯(HEA)反应,制备出端乙烯基聚丙二醇预聚物。此预聚物再与苯乙烯(ST)通过自由基聚合,得到交联的嵌段共聚物。本文对得到的端异氰酸酯和端乙烯基预聚物以及交联的嵌段共聚物进行了表征。更多还原

【Abstract】 A vinyl-terminated prepolymer was prepared by the reaction of hydroxyethyl acrylate (HEA) with isocyanate-terminated prepolymer obtained from polypropylene glycol (PPG) and toluene diisocyanate.The vinyl-terminated prepolymer polymerized with styrene (ST)in the presence of free radical initiator to obtain a crosslinked block copolymer.These prepolymers and the crosslinked block copolymer were characterized.更多还原
