【摘要】 研究端基封闭法合成双环戊二烯（ＤＣＰＤ）改性不饱和聚能工艺条件对产品性能的影响。研究结果表明，合成反应的最佳工艺条件为总酸酐：丙二醇：ＤＣＰＤ＝１：１．１：０．１─０．１６；封端反应温度１３０─１４０℃催化剂量为总重量的０．０２％─０．０３％；聚酯酸值５０ｍｇｋＯＨ·ｇ￣（－１）时滴加ＤＣＰＤ，滴加时间控制在１─２小时；加成反应时间为２小时左右。更多还原

【Abstract】 The effects of process conditions on product property were studied in the synthesis ofDCPD-modified unsaturated polyester by blocking of terminal groups.The results show thatthe optimal conditions of synthesis reaction are as follows:the total anhydride/propyleneglycol/DCPD ratio is l :1.1:0.1-0.16,and when acid value is 50 mgKOH·g￣(-1) with gradualaddition of DCPD,the addition time is l-2h,reaction time is about 2h.更多还原
