Claim 1
Independent Claim
89 words
THE PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT HYDROCARBON POLYMERS WHICH COMPRISES POLYMERIZING AN A-MONOOLEFINIC-HYDROCARBON IN A NORMALLY LIQUID, INERT HYDROCARBON SOLVENT AND WITH A CATALYTIC MIXTURE CONSISTING ESSENTIALLY OF A GERMANIUM HYDRIDE HAVING THE FORMULA: R3GEH, WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF ALKYL RADICALS CONTAINING FROM 1-8 CARBON ATOMS, CYCLOALKYL RADICALS AND PHENYL AND A HALIDE OF A TRANSITION METAL SELECTED FROM THE GROUP CONSISTING OF TITANIUM, VANADIUM, CHROMINUM AND MOLYBDENUM, SAID MIXTURE CONTAINING FROM 0.5-10 MOLES OF GERMANIUM HYDRIDE PER MOLE OF TRANSISTION METAL HALIDE.
