摘　　要：本文以C_(5)馏分、双环戊二烯(DCPD)和C_(9)馏分为原料,在压力2.2-2.6MPa、温度为240℃的条件下,反应10小时,得到浅色的C_(5)/C_(9)共聚石油树脂。适量的C_(5)馏分和DCPD的加入,使原料中活性组份浓度较高,有利于反应进行,同时降低了产品色号。热聚合成反应,不使用催化剂,无废水、废渣产生,工艺绿色环保。In this paper,C_(5)/C_(9) copolymer petroleum resin with light color was obtained from C_(5) fraction,dicyclopentadiene(DCPD)and C_(9) fraction under the conditions of pressure 2.2-2.6MPa and temperature of 240℃for 10 hours.The addition of an appropriate amount of C_(5) fraction and DCPD makes the concentration of active components in the raw material higher,which is conducive to the reaction and reduces the color number of the product.Thermal polymerization synthesis reaction,no catalyst,no wastewater and waste residue,and the process is green and environment-friendly.
