摘要/Abstract

摘要： 低丁二烯含量的丙烯-丁二烯混合单体在负载型钛系催化剂中发生聚合。考察了催化剂Ti浓度、Al/Ti比、苯甲酸乙酯(EB)浓度、聚合温度和聚合溶剂对共聚催化效率、共聚物中丁二烯链节含量和共聚物的比浓粘度的影响。用乙烯基单体在低丁二烯链节含量的共聚物上进行接枝试验,初步结果表明丙烯链上引入不饱和键可以提高其接枝能力。

Abstract: Copolymerization of propylene with small amount of butadiene by using TiCl₄/MgCl₂/AlEt₃/EB catalyst has been carried out. The influences of polymerization temperature, solvent species and concentration of titanium, triethylalu-minum, EBon ca:alytic efficiency, buiadiene unit content, and reduced viscosity of copolymers have been investigated.The copolymer containing 8mol% butadiene unit can be chemically grafted with polar vinyl monomers such as maleic anhydride and methyl methacrylatc in toluene solution in the presence of benzoyl peroxide with ease.
