RADICAL POLYMERIZATION AND COPOLYMERIZATION BEHAVIOR OF N-ACRYLOYL N'-CYANOACETOHYDRAZIDE

The radical polymerization and copolymerization of N-acryloyl N'-cyano acetohydrazide (ACAH), were carried in dimethyl formamide in presence of azobisisobutyronitrile as initiator and kinetic studies on the poly merization behavior of ACAH, conducted. Complex formation of ACAH mono mer and polymer (PACAH) with Cu(II) and Fe(II) cations was investigate d and the stability constant determined. The rate of copolymerization of ACAH with some conventional monomers named vinyl acetate, methyl me thacrylate, and acrylonitrile was measured as a function of mole fract ions of cumonomers. The reactivity ratios (r(1), r(2)) for the various investigated copolymer systems with the Q and e values of ACAH monome r were determined. The thermal gravimetric analysis of prepared polyme r and copolymers with acrylonitrile was done.
