Synthesis of N-vinylcarbazole chromium tricarbonyl and its free radical polymerization reaction

A novel metal chromium containing organic monomer N-vinylcarbazole chromium tricarbonyl has been synthesized and the structure has been confirmed by e lemental analysis, IR and H-1 NMR spectra. N-vinylcarbazole chromium tricar bonyl can undergo free radical polymerization reaction to provide an organo metallic polymer which contains equivalent chromium in its structural unit. It was observed that the decrease of polymerizing activity of the monomer caused by the electron withdrawing effect of Cr(CO)(3) could be compensated to some extent by the conjugational effect between the benzene ring and ni trogen containing electron donor centers.
