ABSTRACT:
Impact modified polycycloolefin is made by ring opening bulk polymerization of at least one monomer containing at least one norbornene group in presence of an organoammonium molybdate or tungstate catalyst and an alkoxyalkylaluminum halide cocatalyst as well as a sufficient amount of a polyolefin powder and a rubbery material to produce ductile polycycloolefin.
