摘要： An article molded from an olefin (co)polymer composition which comprises 0.01 to 5.0 parts by weight of a high-molecular-weight polyethylene having an intrinsic viscosity [θE] of 15 to 100 dl/g as determined in tetralin at 135 °C and 100 parts by weight of a polyolefin, preferably polypropylene, with the high-molecular-weight polyethylene being finely dispersed in the polypropylene in the form of fine particles having a number-mean diameter of 1 to 5000 nm, and which exhibits a high melt tension and a high crystallization temperature that lead to a high productivity in various molding processes. The above composition can be molded into foamed products, films, sheets, laminates, hollow articles, injection-molded products, fibers, non-woven webs, tubular continuous products, and so on. The composition can be prepared by preparing high-molecular-weight polyethylene particles by the use of, e.g., a titanium-containing transition metal catalyst and adding the particles alone or together with a catalyst for the production of polyolefins in the polymerization of an olefin (such as propylene) as the catalyst.

摘要： A plastic molded product of olefin (co)polymer composition comprises 0.01 - 5.0 weight parts high molecular weight polyethylene with an intrinsic viscosity eta E in the range of 15 - 100dl/g measured in 135 DEG C tetralin and preferably 100 weight parts polypropylene. The high molecular weight polyethylene has an average particle size in the range of 1 - 5000nm and is finely dispersed as fine granules in the polypropylene, so that high melt strength and high crystallization temperature are attained, enabling various molding methods to be performed with high speed productivity. Using the polymer composition, plastics such as a resin foam, a film, a sheet, a layered plastic article with a coated substrate surface, a hollow plastic article, an injection molded plastic article, a fiber, a nonwoven web or a continuous tube-shaped plastic are provided. The olefin (co)polymer composition is obtained by preparing high molecular weight polyethylene granules using e.g. a titanium transition metal compound catalyst, and adding these, e.g. as a polymerization catalyst of propylene, singly or together with a polyolefin preparing catalyst.
