"ETHYLENE COPOLYMERS WITH C ~ 3 ~ -C ~ 9 ~ ALPHA-OLEFINS, PROCESS OF PREPARATION OF ETHYLENE COPOLYMERS, POLYMER MIXTURE, USE OF ETHYLENE COPOLYMERS WITH C ~ 3 ~ -C ~ 9 ~ ALPHA-ELEPHAS , FIBERS, WOOLS AND MOLDED BODIES ". Ethylene copolymers WITH C ~ 3 ~ -C ~ 12 ~ 244 -olefins, which have a Mw / Mn mass distribution of 243 10 at a density of 0.85 to 0.95 g / cm ^ 3 ^ , a comonomer portion of 1 to 40% by weight of comonomer and a Mn molar mass greater than 150,000 g / mol, and whose index of the distribution range of the comonomer composition is greater than 70%, a process for its preparation and its use, as well as fibers, molded bodies, sheets or mixtures of polymers containing these copolymers.
