环氧树脂与HET酸型不饱和聚酯树脂的嵌段共聚物

A STUDY ON THE SYNTHESIS AND PROPERTIES OF EPOXY-HET ACID TYPE UPR SEGMENTED COPOLYMER

研究了以环氧树脂与ＨＥＴ酸型不饱和聚酯树脂的嵌段共聚物的基本合成原理、方法和反应条件，讨论了反应温度、催化剂的种类和用量对合成反应的影响及环氧树脂含量对共聚物性能的影响，利用差热分析（ＤＴＡ）、热重分析（ＴＧ）对嵌段共聚物树脂的热解过程进行了初步的讨论。

A study was made on the synthesis and properties of epoxy-HET acid type UPR segmented copolymer.The effect of temperture,kinds and weight of catalyst on the synthesis reaction as well as the content of epoxy resin on the properties of segmented copolymer were discussed.The primary study was conducted with differential thermal analysis(DTA) and thermogravimetry(TG) on the pyrolysis of the segmented coplymer resin.
