## Abstract Ethyleneβpropylene random copolymer with ultraβhigh molecular weight (UHPPR) and broad molecular weight distribution (MWD) was prepared with ZieglerβNatta catalyst. The viscoelastic behavior of UHPPR has been investigated by means of oscillatory rheometer at 180, 200 and 220 Β°C. The los
