(FR) RESINES DE POLYETHYLENE
Abstract
(EN)
The invention provides ethylene/α-olefin copolymers exhibiting improved environmental stress cracking resistance properties, and methods for the production of the copolymers in a single reactor by means of a bimetallic catalyst including a Ziegler component and a metallocene component.
