摘　　要：石油树脂原料中加入α-甲基苯乙烯进行改性时,将催化剂AlCl_3溶于二甲苯中,当α-甲基苯乙烯加入量为10%(质量分数)时,可制备出高溶解性、低色度、适宜软化点、优良增粘效果和优良热稳定性的高性能间戊二烯石油树脂,可广泛的应用在热熔胶及热熔压敏胶等领域。Modifying by addingα-methylstyrene into piperylene,the raw material of petroleum resin,and AlCl 3 as catalyst together dissolved in xylene.When 10%wt ofα-methylstyrene is added,the high-performance pentadiene petroleum resin is produced with high solubility,low color,suitable softening point,excellent thickening effect and excellent thermal stability which can be widely used in the fields of hot-melt adhesives and hot-melt pressure-sensitive adhesives.
