Abstract
Alpha-monoalkenes are addition polymerized by using an acyl halide (e.g., acetyl chloride)--Friedel Crafts catalyst complex and a monochloroalkane solvent (e.g., ethyl chloride); the acyl halide reacts in situ with the monomer to yield a polymeric ketone. The polymeric ketone is subsequently reacted with an aliphatic polyamine (e.g., tetraethylenepentamine) to yield a condensation product which is useful as a lube oil detergent.
