摘要
简要介绍了不饱和聚酯的主要性质及用途；研究了以废聚酯瓶片为主要原料，辅以多元醇和多元酸制备新对苯型（ＸＤＢ－１）不饱和聚酯树脂的原理和方法；分析讨论了反应温度、催化剂种类、原料组成和配比等对反应过程及产品主要性能的影响。
The properties and applications of unsaturated polyester resin were in troduced. The principle and method of producing XDB-1 type of unsaturated polyester resin from waste PET bottles as the main raw material and polyacid and polyalcohol as auxiliary material were studied. And the effect of reaction temperature ,catalyst varieties and monomer components on the reaction and properties of the product were discussed.
