    • The present invention relates to a process for preparing a high impact monovinylaromatic polymer comprising admixing a rubber, at least one monovinylaromatic monomer and optionally one or more comonomer in the presence of at least a borane complex of the L-BH3 type wherein L is a Lewis base and polymerizing the monovinylaromatic monomer.The borane complex initiator, L may be an ether (e.g THF, tetrahydrofurane), a thioether (e.g dimethylthioether) or an amine. A preferred complex is an amine borane such as by way of example triethylamine borane.The present invention also relates to a high impact monovinylaromatic polymer having a weight ratio of grafted monovinylaromatic monomer and optional comonomer to the initial monovinylaromatic monomer and optional comonomer above 0.1%, advantageously above 2% and preferably in the range 2 to 4%.The invention is of particular interest to make high impact polystyrene.
    • 本发明涉及一种制备高冲击单乙烯基芳族聚合物的方法,包括在至少一种L-BH3型的硼烷配合物存在下将橡胶,至少一种单乙烯基芳族单体和任选的一种或多种共聚单体混合,其中L是路易斯 碱化并聚合单乙烯基芳族单体。 硼烷络合物引发剂L可以是醚(例如THF,四氢呋喃),硫醚(例如二甲基硫醚)或胺。 优选的络合物是胺硼烷,例如通过例如三乙胺硼烷。 本发明还涉及具有接枝单乙烯基芳族单体和任选的共聚单体与初始单乙烯基芳族单体和任选的共聚单体的重量比高于0.1%,优选高于2%,优选2至4%的高冲击单乙烯基芳族聚合物。 制造高抗冲聚苯乙烯的本发明是特别有意义的。
