摘要
本文以丙烯酸酯封端的聚硫橡胶（Ａｃｒｙ－ＬＰ），环氧封端的聚硫橡胶（ＥＰ－ＬＰ）分别同双酚Ａ环氧树脂（ＥＰ－５１）合成互穿网络和共聚网络，并研究了它们的相结构和性能。结果表明，所有样品都具有低温柔顺性和良好的力学性；对于Ａｃｒｙ－ＬＰ／ＥＰ－５１网络，低分子量Ａｃｒｙ－ＬＰ有利于互穿；对于ＥＰ－ＬＰ／ＥＰ－５１共聚网络，高分子量ＥＰ－ＬＰ有利于提高相容性。
Acrylate terminated liquid polysulfide (Acry LP) and epoxy terminated liquid polysufide(EP LP) react with epoxy resins containing bisphenol A to make interpenetrating and copolymer networks respectively All samples have low temperature properties, good tensile strength properties Acry LP/EP 51 with lower M W facilitates to form better interpenetrating structure, while EP LP/EP 51 with hige M W makes the copolymer networks very compatible
