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。
The effect of process conditions of end-capped synthesis of dicyclopentadiene (DCPD) on the performance of the product was studied. The results showed that the optimal conditions for the synthesis reaction were total anhydride: propylene glycol: DCPD = 1: 1.1: 0.1─0.16; the reaction temperature was 130 ~ 140 ℃, the total amount of catalyst was 0.02 % -0.03%; polyester acid value of 50mgkOH · g ~ (-1) dropping DCPD, dropping time control in 1 ─ 2 hours; addition reaction time is about 2 hours.
