端羧酸丁腈橡胶环氧基酯增韧剂的合成与应用

The synthesis and application of carboxy terminal butadiene-acrylonitrile epoxy ester toughner

采用端羧酸丁腈橡胶(CTBN)来合成1种新型的CTBN环氧基酯增韧剂。介绍了该增韧剂的合成工艺路线和条件。并通过应用实例阐述了该增韧剂在环氧固化体系中的应用效果。结果表明:加入一定量的催化剂可有效地提高酯化反应的速率;该增韧剂对环氧树脂固化体系有显著增韧效果。

A novel toughner for epoxy resin, carboxy terminal butadiene-acrylonitrile （CTBN） epoxy ester, was synthesised from CTBN and epoxy resin and its synthetic process and application in toughning comon epoxy resin curing system were also introduced in this paper. The synthetic reaction rate was increased by catalyst and the toughner had significant level for toughning epoxy resin curing system.
