摘要:
The present invention relates to a butadiene/acrylonitrile copolymer CTBN, modified by epoxy solid resin and terminated by carboxyl groups, the terminal epoxy groups thereof also having optionally been reacted. A polymer of this type is used in particular as an impact strength improving agent in epoxy resin compositions and has proven to be particularly advantageous for gluing on or of metal surfaces. It results in a significant reduction of the infiltration with corrosion, which in turn ensures a long-lived adhesive bond.
摘要(中):
本发明涉及由环氧固体树脂改性并被羧基封端的丁二烯/丙烯腈共聚物CTBN,其末端环氧基也可任选地反应。 这种聚合物特别用作环氧树脂组合物中的冲击强度改进剂,已被证明是特别有利于胶合在金属表面上。 这导致了腐蚀性渗透的显着降低,这又确保了长久的粘合剂粘结。
