摘　　要：本文以C_(5)馏分、双环戊二烯(DCPD)和C_(9)馏分为原料,采用两段热聚合成法进行共聚反应制备C_(5)/DCPD/C_(9)共聚石油树脂。首先以C_(5)馏分为原料,在温度240℃、压力5.5MPa的条件下,热聚合反应6h,得到C_(5)低聚物,然后再将C_(5)低聚物、DCPD、C_(9)馏分三者的混合物,在压力0.40MPa~0.55MPa、温度为250℃的条件下,反应3~8h,得到色号为3.0~4.0的浅色石油树脂。In this paper,C_(5)/DCPD/C_(9) copolymer petroleum resin was prepared by two-stage thermal polymerization with C_(5) fraction,dicyclopentadiene(DCPD)and C_(9) fraction as raw materials.Firstly,C_(5) fraction is used as raw material,which is polymerized for 6h under the conditions of temperature 240℃and pressure 5.5MPa to obtain C_(5) oligomer.Then,the mixture of C_(5) oligomer,dicyclopentadiene(DCPD)and C_(9) fraction is reacted for 3-8 hours under the conditions of pressure 0.40-0.55MPa and temperature 250℃to obtain light colored petroleum resin with color number 3.0-4.0.
