摘　　要：以高活性聚异丁烯和苯酚为起始原料,通过烷基化反应合成对聚异丁烯苯酚(PIBP),考察催化剂、溶剂、温度和时间对PIBP选择性的影响。结果表明,四氯化锆为催化剂,正己烷为溶剂,在100℃反应3 h,能够得到高选择性的对聚异丁烯苯酚,产物具有较高的热稳定性。p-Polyisobutylene phenol is synthesized from highly active polyisobutylene(PIB)and phenol via alkylation reaction.Through the optimization of the catalyst,solvent,temperature and time in the reaction process,the results showed that high selectivity of p-isobutylene phenol could be obtained by the reaction of n-hexane with zirconium tetrachloride as catalyst at 100℃for 3 h,the product has high thermal stability.
