摘要
本文以丙烯酸乙酯、丙烯酸丁酯为主要单体，以丙烯酸甲氧基乙酯为共聚单体，以ＧＭＡ或ＡＧＢ为硫化点单体，采用乳聚法合成了含环氧交联点的低温（Ｔｇ＝－２８℃）丙烯酸酯橡胶（ＡＣＭ），生胶凝胶含量小于１％，并用ＩＲ、１Ｈ－ＮＭＲ表征了共聚物的结构；ＤＳＣ测定出共聚物的Ｔｇ为－２８℃。并考察了不同聚合工艺对生胶性能的影响。
n this paper,oil and low temperature resistant ACM containing epoxy group was synthesized by means of emulsion copolymerization using ethyl acrylate,butyl acrylate,2-methyoxy ethyl acrylate as comonomers and glycddyl methacrylate,allyl glycdyl ether as crosslinking monomer.The title copolymer was characterized by IR,1H-NMR and DSC.The gel content of copolymer is no more than 1%,Tg is 28℃.
