ABSTRACT:
A catalyst system comprising (I) an organoaluminum compound, (II) an organophosphine compound, and (III) a metal salt of a beta-diketone, is effective to homopolymerize an alkene oxide, homopolymerize an ester of acrylic or methacrylic acid or certain other vinyl monomers, or to copolymerize an alkene oxide with an ester of acrylic or methacrylic acid or certain other vinyl monomers. Suitable vinyl monomers include vinyl esters, vinyl ethers, or vinyl ketones.
