摘要： The present invention relates to a polyolefin pellet for preparing a fiber, and a fiber comprising the same. According to the present invention, provided is a polyolefin, which exhibits a high molecular weight range and a narrow molecular weight distribution and in which the formation of a gel deteriorating the quality of a fiber is reduced. Therefore, the present invention has high strength and an excellent drawing characteristic and is capable of high orientation since the gel formation is reduced, while exhibiting a molecular weight, a density and a narrow molecular weight distribution, which are equivalent to those of a conventional polyolefin, by using the polyolefin pellet, and thus the present invention can be applied to various industrial products due to high drawing ratio and crystallinity during a multifilament operation using the same.

摘要： The present invention concerns a heterogeneous catalyst for polymerization of olefins. The catalysts include at least one group IVa metal compound on a solid inorganic oxidic support. According to the invention the catalysts are prepared by vapourizing at least one solid group IVa metal halide compound and routing the vapour of the metal halide compound into a reaction chamber, wherein the vapour is reacted with the support at a temperature of about 250 to about 450 DEG C in order to bind said metal halide compound to said support. Any metal compound not bound to said support as well as any volatile reaction products emanating from the reaction between said metal halide compound and said support are then removed from the reaction chamber in the vapour phase. Optionally the product obtained is treated with an organic aluminum compound to increase the catalytic activity of said catalyst. The catalysts thus prepared are very well suited for polymerization of ethylene or copolymerization of ethylene with other alfa-olefins, such as propylene, butylene, 4-methyl-1-pentene and hexene. A polymerization process employing the novel catalyst will provide products of the Ultra High Molecular Weight-type (UHMWPE) having very broad MWD.

摘要： A suspension which comprises an inert liquid medium, a solid material, and a transition metal compound is dried using a spray-drying technique. The spray-drying is effected under conditions of temperature and pressure which are such as to cause evaporation of the liquid medium. The solid material is preferably in a finely-divided form. The solid material may consist essentially of a transition metal compound or may be a transition metal compound which is supported on a suitable solid inert matrix material. Alternatively, a suspension of a solid support material in a solution of a transition metal compound may be used. The dried solid is obtained as an agglomerate. The agglomerated solid can be mixed with an organic compound of a non-transition metal to give an olefin polymerisation catalyst system.

摘要： An improved solid Ziegler-Natta type catalyst for the (co)polymerisation of ethylene and α-olefins, particularly in high-temperature processes, such as for example adiabatic solution processes and high-pressure adiabatic processes with elevated productivity, is provided. Said catalyst is obtained by means of an original process comprising dissolving in hydrocarbons, compounds of titanium, magnesium and optionally a metal selected from hafnium and zirconium, and reprecipitating them in two steps in succession, the first of which is chlorination and the second reduction.
