低分子量链烯烃（共）聚合物制造用聚合催化剂
摘要：
本发明涉及一种链烯烃聚合用催化剂，其含有(A)用下述通式(1)表示的第4族过渡金属化合物，和(B)选自(B-1)用通式RaRbM3表示的周期表第2族或第12族金属的二烷基化合物，式中Ra以及Rb可以相同也可以不同，表示碳原子数为1～15的烃基，M3是Mg、Zn或Cd；(B-2)有机铝化合物；(B-3)有机铝氧化物；(B-4)与上述第4族过渡金属化合物(A)反应形成离子对的化合物中的至少一种化合物，适用于使链烯烃单聚或共聚以制造低分子量链烯烃(共)聚合物，其中，R为氢、烃基、含硅基，M是Ti、Zr或Hf，Y是第14族原子，Q为卤素、烃基、中性、共轭或非共轭二烯烃、阴离子配位基以及可通过孤对电子配位的中性配位基，n为2～4的整数，j为1～4的整数。
摘要（英）：

The invention relates to a catalyzer for polymerize olefins, which contains (A):compound of transition metal of the forth group denoted by formula(1) and (B): dialkyl compound(B-1) of metal element of the second or the twelfth group in the periodic table of elements denoted by the general formula of RRM<3>; wherein R and R, which can be the same or different, denote alkyl with 1-15 carbon atoms; M<3> is Mg, Zn or Cd; (B-2) is organic aluminum compound, (B-3) is organic alanate, and (B-4)is at least one of the compounds which can produce ionpair with the compound(A) of transition metal of the forth group after reaction. The catalyzer is suitable for producing olefine polymer with small molecular weight; wherein R is hydrogen, alkyl or silaceous group, M is Ti, Zr or Hf, Y is atom from the fourteenth group, and O is halogen, alkyl, neutral, conjugated or non-conjugated diolefine, complex anion radicel or neutral dentate which can be coordinated through lone electron pairs; nis an integer among 2-4 and j is an integer among 1-4.
