The procedure of Comparative Example 2 was followed except that the catalyst used was 5×10−7 mol of rac-[(ind)Et2PBCl2(ind)ZrCl2] activated with 5×10−3 mol of MAO. The internal pressure was raised by 2 bar with ethylene. The polymerization took place in the presence of 1 g of ethylidenenorbornene (ENB). The terpolymer formed (1.5 g) contained 63 wt. % of ethylene, 35 wt. % of propylene and 2 wt. % of ENB. The intrinsic viscosity in ortho-dichlorobenzene at 140° C. was 1.86 dl/g. The GC measurement in o-Cl2-benzene at 140° C. gave Mw=460 kg/mol and Mn=203 kg/mol. The DSC measurement in the 2nd heating indicated an amorphous polymer with a glass transition temperature Tg of −50° C.
