Claim 1
Independent Claim
107 words
A PROCESS FOR PREPARING AN ALUMINUM HYDRIDE POLYMERIZATION ACTIVATOR WHICH COMPRISES FORMING A REACTION MIXTURE CONSISTING ESSENTIALLY OF POWDERED ALUMINUM CHLORIDE, SUFFICIENT OF A POWDERED METAL HYDRIDE TO REACT WITH ALL OF THE HALOGEN OF SAID ALUMINUM HALIDE, AND AN INERT LIQUID HYDROCARBON DISPERSING MEDIUM, AND AGITATING SAID MIXTURE AT A TEMPERATURE BETWEEN ABOUT 20* AND 100*C. UNTIL SAID ALUMINUM HALIDE IS CONVERTED TO ALUMINUM HYDRIDE, SAID REACTION BEING CARRIED OUT IN THE ABSENCE OF WATER, AIR, AND COMPOUNDS CAPABLE OF FORMING COMPLEXES WITH ALUMINUM HYDRIDE, SAID METAL HYDRIDE BEING SELECTED FROM THE CLASS CONSISTING OF ALKALI METAL HYDRIDES, ALKALINE EARTH METAL HYDRIDES, AND ALKALI METALALUMINUM HYDRIDES.
