Aluminum chloride catalyzed polymerization process

Claim 1

IN A PROCESS WHEREIN NORMALLY GASEOUS OLEFINS SELECTED FROM THE CLASS CONSISTING OF PROPYLENES, BUTYLENES, AND MIXTURES THEREOF ARE POLYMERIZED WITH AN ALUMINUM CHLORIDE CATALYST TO FORM A REACTION MIXTURE COMPRISING OLEFIN POLYMER IN ADMIXTURE WITH ALUMINUM CHLORIDEHYDROCARBON COMPLEX, AND WHEREIN AT LEAST A PORTION OF SAID REACTION MIXTURE IS TREATED WITH ANHYDROUS AMMONIA TO FORM A SEPARABLE ALUMINUM CHLORIDE-AMMONIA COMPLEX, THE IMPROVEMENT COMPRISING COMMIMGLING SAID PORTION WITH SUFFICIENT EXCESS LIQUID ANHYDROUS AMMONIA TO DISSOLVE SAID ALUMINUM CHLORIDE-AMMONIA COMPLEX, AND THEREAFTER SEPARATING THE RESULTING COMPLEX-FREE HYDROCARBON PHASE FROM AN IMMISCIBLE LIQUID AMMONIA PHASE CONTAINING THE DISSOLVED ALUMINUM CHLORIDE-AMMONIA COMPLEX.
