  • Process for the polymerization of propylene
    Patent number: 9988474
    Abstract: The invention relates to a process for the preparation of ethylene-propylene copolymers having —a weight average molecular weight of 800,000-1,800,000, —a molecular weight distribution of 3-8, —an ethylene content of 1-10 wt %, preferably 1.5 to 5.5 wt %. —a melt flow in the range of 1.5-8 dg/min measured with a load of 21.6 kg at 230° C. and —a xylene soluble content of 2-15 wt % by converting propylene into the UHMWEP copolymer without pre-polymerization in the presence of a polymerization catalyst under a condition where the volume ratio of H2 to propylene is at most 0.
