COPOLYMERS OF ETHYLENE WITH C3-C12 .ALPHA. OLEFINS

摘要

The invention relates to copolymers of ethylene with C3-C12 .alpha. olefins which have a molecular weight distribution Mw/Mn of .ltoreq. 10, a density of 0.85 to 0.95 g/cm3, a comonomer share of 1 to 40 % by weight and a molar mass Mn of more than 150000 g/mol. The index of breadth of the composition distribution of the comonomer is more than 70 %. The invention also relates to a method for producing said copolymers and to their use as well as to fibers, molded articles, films or polymer mixtures that contain said copolymers.
