摘要: 聚酯-聚醚多嵌段共聚物同少量的环氧树脂等共混,可以改善共混物作热熔胶使用时的剪切强度、剥离强度和热光老化性能.本文研究了共混条件,同时根据IR、DTA、TM和TG实验结果,提出了在熔融粘接过程中,环氧基同共聚物端羟、羧基反应的可能性.

Abstract: The shearing, Peeling strength and thermo and photo-resistance of polyester-polyeether blockcopolymer were improved by adding cresol-formaldehyde epoxide resin. The conditions of blending were searched and a mechanism of blending has been ProPosed basedon IR, DTA, TM and TG measurements. It is shown that the reaction cf ePoxide group with the end group (-OH, -COOH) of polyester-polyether takes place during the melting of the blends.
