    摘要： Process for the preparation of an ethylene copolymer composition having a polydispersity index Mw/Mn of from 3 to 100, comprising a) feeding ethylene to at least one polymerization reactor; b) performing in the at least one polymerization reactor an oligomerization of ethylene in the presence of an oligomerization catalyst component (C) to produce comonomer; c) performing simultaneously in the at least one polymerization reactor polymerization reactions in the presence of catalyst components (A) and (B) producing, respectively, a first and a second polyethylene fraction, wherein the weight average molecular weight Mw of the first polyethylene fraction produced by catalyst component (A) is less than the Mw of the second polyethylene fraction produced by catalyst component (B) and the comonomer incorporation ability of catalyst component (B) is higher than the comonomer incorporation ability of catalyst component (A); and d) withdrawing the ethylene copolymer composition from the polymerization reactor.
