    • A process for producing an aromatic vinyl compound copolymer wherein the aromatic vinyl chain has a highly syndiotactic structure, which process comprises copolymerizing an aromatic vinyl compound with, for example, an olefin in the presence of a catalytic system comprising (A) a transition metal compound, (B) an ionic compound comprising a noncoordinating anion and a Group 4 typical element cation, and optionally (C) a Lewis acid. This process enables an efficient production of an aromatic vinyl compound copolymer which is reduced in the content of residual ash and residual poisonous matter and wherein the aromatic vinyl chain has a highly syndiotactic structure without the necessity for using a costly aluminoxane by using a high-activity catalytic system.
    • 一种芳族乙烯基化合物共聚物的制备方法,其中芳族乙烯基链具有高间规结构,该方法包括在催化体系存在下使芳族乙烯基化合物与例如烯烃共聚,所述催化体系包含(A)过渡金属化合物 ,(B)包含非配位阴离子和第4族典型元素阳离子的离子化合物,和任选地(C)路易斯酸。 该方法能够有效地生产芳族乙烯基化合物共聚物,其降低了残余灰分和残留的有毒物质的含​​量,并且其中芳族乙烯基链具有高度间同立构结构,而不需要使用昂贵的铝氧烷通过使用高活性 催化体系。
