There are provided (I) a process for producing a copolymer of ethylene, an α-olefin having from 3 to 20 carbon atoms and optionally a polyene, which comprises the step of copolymerizing those monomers in a polymerization reactor by feeding the following components (A), (B), (C1) and (D) to the polymerization reactor: (A) a transition metal complex, (B) an organic aluminum compound, (C1) a halogen-containing compound, and (D) a Lewis base, wherein those components are fed to the polymerization reactor without a preliminary contact of (1) the component (A) with the component (B), (2) the component (A) with the component (C1), (3) the component (B) with the component (C1), and (4) the component (B) with the component (D); and (II) a process for producing said copolymer, which comprises the step of copolymerizing those monomers in a polymerization reactor (i) by feeding to the polymerization reactor the components (A), (B), (D), (C2) a halogen-containing compound, which is a derivative of an aryl group-containing carboxylic acid, and (C3) a halogen-containing compound, which is not a derivative of a carboxylic acid, or (ii) by feeding thereto the components (A), (B), (D), (C3), and (C4) a halogen-containing compound, which is a derivative of a carboxylic acid containing an unsaturated bond-carrying linear organic group.
提供了(I)一种生产乙烯、具有 3 至 20 个碳原子的α-烯烃和任选的一种聚烯的共聚物的工艺,该工艺包括在聚合反应器中通过向聚合反应器加入下列组分(A)、(B)、(C1)和(D)使这些单体共聚的步骤:(A)过渡金属络合物,(B)有机铝化合物,(C1)含卤素化合物,和(D)路易斯碱,其中这些组分在送入聚合反应器时不需要(1)组分(A)与组分(B),(2)组分(A)与组分(C1),(3)组分(B)与组分(C1),和(4)组分(B)与组分(D)的初步接触;和(II) 生产所述共聚物的工艺,该工艺包括在聚合反应器(i)中通过向聚合反应器加入组分(A)、(B)、(D)、(C2)含卤素化合物(含芳基羧酸的衍生物)来共聚这些单体的步骤、和 (C3) 含卤化合物,它不是羧酸的衍生物,或 (ii) 向反应器中加入组分 (A)、(B)、(D)、(C3) 和 (C4) 含卤化合物,它是含有不饱和键载线性有机基团的羧酸的衍生物。
