The Preparation, Polymerization and Copolymerization of Substituted Derivatives of Cynichrodene (eta5-C5H5)Cr(CO)2NO.

Abstract

The novel vinyl organometallic monomer (vinyl-cyclopentadienyl)-dicarbonylnitrosylchromium (hereafter called vinylcynichrodene), was prepared and homopolymerized and copolymerized in solution and neat using azo initiators. Reactivity ratios were obtained in radical initiated copolymerizations with styrene and N-vinyl-2-pyrrolidone. When M2 was styrene, r1 = 0.30 and r2 = 0.82. The value of the Alfrey-Price parameter e for vinylcynichrodene was -1.98 and the resonance interaction parameter Q was 3.1. copolymerizations with N-vinyl-2-pyrrolidone (M2) gave r1 = 5.3, r2 = 0.079 and e = -2.07. Thus, vinylcynichrodene is an exceptionally electron-rich vinyl monomer resembling vinyl-ferrocene and vinylcymantrene. Vinylcynichrodene readily copolymerized with vinylcymantrene. (Author)
