ORGANOMETALLIC POLYMERS.

The homopolymerization kinetics of ( eta **5-vinylCp)W(CO)//3CH//3 and ( eta **5-vinylCp)Cr(CO)//2NO were studied. Copolymerization of several eta **5-vinylCp monomers with styrene, methyl acrylate, acrylonitrile and N-vinylpyrrolidone were conducted using radical initiation. From the reactivity ratios, values of the Alfrey-Price Qe parameters were obtained, illustrating that all of the metallic monomers studied were exceptionally electron rich. Cationic initiation of the ( eta **5-isopropenylCp)-metal type monomers gave low molecular weight homopolymers and copolymers at best. The syntheses of 1,1 prime -bis( beta -aminoethyl)ferrocene and their interfacial polycondensation with both diacid chlorides and diisocyanates was conducted.
