大连理工大学以二乙烯基苯(DVB)为偶联剂,环己烷为溶剂,通过阴离子聚合制备了星形苯乙烯-异戊二烯-丁二烯三元无规共聚物(SSIBR);以环烷酸镍和三异丁基铝作为催化剂,在60℃和4.0MPa氢压下反应4h,制备了氢化度为100%的氢化星形苯乙烯-异戊二烯-丁二烯三元无规共聚物(HSSIBR)。考察了DVB/Li用量、单臂相对分子质量对聚合物偶联效率(CE)和加氢反应
The star - stirene - isoprene - butadiene ternary random copolymer (SSIBR) was prepared by anionic polymerization using divinylbenzene (DVB) as coupling agent and cyclohexane as solvent. Hydrogenated star-shaped styrene-isoprene-butadiene ternary was prepared with 100% degree of hydrogenation using nickel naphthenate and triisobutylaluminum as catalysts under 60 ℃ and 4.0MPa hydrogen pressure for 4h. Random Copolymer (HSSIBR). The effects of DVB / Li dosage, relative molecular weight of one arm on the coupling efficiency (CE) and hydrogenation
