BESTRAHLTES ETHYLEN-POLYMER MIT HOHER SCHMELZFESTIGKEIT

Disclosed is a normally solid, high molecular weight, gel-free, irradiated ethylene polymer having a density of from 0.89 to 0.97 g/cc characterized by high melt strength due to strain hardening which is believed to be caused by free-end long chain branches of the molecular chains forming the polyme...

description	Disclosed is a normally solid, high molecular weight, gel-free, irradiated ethylene polymer having a density of from 0.89 to 0.97 g/cc characterized by high melt strength due to strain hardening which is believed to be caused by free-end long chain branches of the molecular chains forming the polymer. Also disclosed is a process for making the polymer by high energy radiation of a normally solid, high molecular weight, ethylene polymer in a reduced active oxygen environment, maintaining the irradiated material in such environment for a specific period of time, and then deactivating free radicals in the material.
