摘要: 环氧树脂改性一直是比较活跃的研究领域, 近 20 多年来国外相继成功开发了多种具有活性端基低分子量液体橡胶, 如丁腈橡胶、聚硫橡胶、聚丙烯酸酯等环氧树脂改性增韧剂[1~5].然而, 尽管聚醚原料易得, 并具有优异柔性和耐低温性能, 但由于聚醚与环氧树脂相容性差或缺乏直接键合作用, 长期以来聚醚改性环氧树脂报道并不多见. 我们使用甲苯二异氰酸酯和丙烯酸- -羟乙酯对双端羟基环氧丙烷聚醚进行封端, 解决了两者键合问题, 从而开辟了一条新的改性环氧树脂途径。

Abstract: Poly(propylene oxide)containing two acrylate end groups was prepared firstly by reaction of poly(propylene oxide)with tolylene diisocyanate and 2-hydroxyethylene acrylate. Then it was used as a reactive modifier for epoxy resins of diglycidyl ether of bisphenol A type in the presence of curing agent containing amine groups. Due to the linkage between acrylate end groups and curing agents, the compatibility of epoxy resin with modifiers was improved.

Key words: epoxyresin, poly propylene oxide, blend, preparation
