    摘要： Disclosed is a novel ethylene copolymer by copolymerizing an ethylene and at least one comonomer selected from a compound represented by the formula H2C═CHR wherein R is an alkyl group or an aryl group, and a diene, by slurry polymerization process in the presence of a solid catalyst system comprising a support, a transition metal compound and an activator capable of converting the transition metal compound into a catalytically active transition metal complex. The produced copolymer has a density of from 0.870 to 0.980 and a molecular weight distribution (Mw/Mn) of from 3 to 10, and exhibiting GPC/FT-IR characteristics and CFC characteristics, both of which define a comonomer content distribution, wherein, in one aspect, the lower the molecular weight of a copolymer fraction in a molecular weight distribution of an ethylene copolymer, the lower the comonomer content of the copolymer fraction; and, in the other aspect, the higher the molecular weight of a copolymer fraction, the higher the comonomer content of the copolymer fraction, so that ethylene copolymer exhibits high impact strength and excellent ESCR properties. Further, the ethylene copolymer contains substantially no impurites such as a wax, a gel and the like. Thus, the ethylene copolymer and blend compositions therefrom can be advantageously used for the production of film, fibers, foams or sheets including blown film, cast films, laminate films, blow-molded articles, injection molded articles, pipes, coating materials for cables, and the like.

    摘要： A supported catalyst component prepared from a support material and an alumoxane, containing 15-40 weight percent of aluminum from the alumoxane (based on the total weight of the support material and alumoxane), said supported catalyst component being obtained by heating said support material and alumoxane under an inert atmosphere at a temperature of from about 85 to about 250.degree. C. for a period sufficient to fix said alumoxane to the support material, to provide a supported catalyst component; wherein not more than about 10 percent aluminum from said alumoxane and present in the supported catalyst component is extractable in a one-hour extraction with toluene at 90.degree. C. using 10 ml toluene per gram of supported catalyst component; and a transition metal compound, and a process for the preparation of the supported catalyst.
