Abstract
Copolymers of ethylene with C-Cα-olefin have a polydispersity Mw/Mn of ≦10, a density of from 0.85 to 0.95 g/cm, a proportion of from 1 to 40% by weight of comonomer and a molar mass Mn above 150,000 g/mol and a comonomer composition distribution breadth index above 70%. A process for their preparation is described, as are their use and fibers, moldings, films and polymer mixtures comprising these copolymers.
