Abstract
Monomers having a norbornene as polymerizable group and a 2,2,6,6-tetr amethyl piperidine as stabilizing moiety were prepared. This monomer w as successfully copolymerized with ethylene using VAc3/AlEt2Cl as the catalytic system. Copolymers exhibited better stability under accelera ted aging than polyethylene stabilized by classical blending with comm ercial hindered amines. Any attempt made to obtain copolymers using a high activity TiCl4/MgCl2 catalyst was unsuccessful. (C) 1994 John Wil ey & Sons, Inc.
