摘要 采用催化水解加成法研究了“工业级”双环戊二烯为主要原料合成不饱和聚酯树脂的新工艺及性能。双环戊二烯的含量低于80%,研究了各种影响因素,得出主要工艺条件:加成温度为120~140℃,酯化温度为170~180℃,n(顺丁烯二酸酐):n(邻苯二甲酸酐)=(5~6):1,n(DCPD):n(顺丁烯二酸酐)=(0.5~0.8):1,催化剂用量为0.1%~0.2%,树脂收率达93.5%~94.8%。 The new process and property of unsaturated polyester resin synthesized with industrial grade dicyclopentadiene (DCPD) as raw material were investigated by means of catalyst hydrolysis addition method, in which the content of DCPD was less than 80 %. The effect of different factor was investigated and the main process conditions were obtained: additive temperature 120 - 140℃, esterification temperature 170 - 180 ℃, n(maleic anhydride): n (phthalic anhydride) = 5 ~ 6:1 (mol: mol), n (DCPD) : n (maleic anhydride) = 0.5 ~ 0.8:1 (mol: mol), the content of catalyst was 0.1% -0.2% .The yield of the resin came up to 93.5% -94.8%.
