Abstract: Graft copolymers with polyethylene (PE) backbone and polystyrene (PS) grafts were prepared by copolymerization of norbornene-capped polystytene macromer (PS-NB) with ethylene using Ziegler-Natta catalysts. Purified products were characterized by GPC and IR.The relatively low conversion of PS-NB was attributed to micro-phase separation in the copolymerization. The graft copolymers exhibited mechanical properties similar to those of PE obtained with tbe same catalyst system.
