    摘要: The present invention belongs to the field of polyolefin alloy preparation, and particularly relates to a polyolefin composite material in good form with adjustable composition and performances, produced by controlling a composite catalyst composed of Zieglar-Natta catalyst and metallocene catalyst to be catalytic by stage in the olefin polymerization reaction. This material is composed of propylene polymer and ethylene copolymer which is obtained by copolymerizing ethylene with alpha olefin or diolefin, wherein: the molar content of alpha olefin or diolefin in the ethylene copolymer is 0%˜60%, and the ethylene copolymer is 3˜80% by weight of the polyolefin composite material; the polyolefin composite material is in particle form, and the ethylene copolymer has a molecular weight distribution of 1˜6 and a glass transition temperature of −80˜0° C.; and the ethylene copolymer produced in the reaction is dispersed homogeneously in the propylene polymer particles to form the polyolefin composite material.

    摘要: The invention relates to linear copolymers containing alpha-olefin and divinylbenzene comonomer units and to a process for preparing the copolymers, the copolymers having a mole ratio of unsaturation/divinylbenzene (TUS/DOU) between 0.8 and 1.1, a molecular weight distribution of less than 4, and a homogeneous composition distribution, and having the structural formula ##STR1## in which R is a linear or branched C.sub.1 to C.sub.10 alkyl group or a phenyl or alkyl-substituted phenyl group, x+y is the mole % of alpha-olefin units in the copolymer, z is the mole % of divinylbenzene units in the copolymer, the sum of x+y is from 50 to 99.9, and the sum of x+y+z is 100. The copolymers are prepared in the presence of a bridged metallocene catalyst having a spacial opening at the metal active site of between 135 and 105.degree. for reacting with only one of the two vinyl groups in the divinylbenzene comonomer, which assures the formation of linear copolymers without detectable branching structure.
