摘要： The invention pertains to a method for the preparation of ultra high molecular mass polyethylene by polymerization in suspension or in gas phase in the presence of a chromium catalyst sitting on an alumosilicate support material. The chromium catalyst has been subjected to a fluorinating treatment and the polymerization is performed under low temperature conditions within a temperature range of from 50 to 100° C. The invention pertains also to ultra high molecular mass polyethylene prepared by that method and having a density in the range of from 0.930 to 0.950 g/cm3.

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.
