Radical Polymerization and Copolymerization Behavior of N-Acryloyl N′-Cyanoacetohydrazide

Abstract

ABSTRACT:The radical polymerization and copolymerization of N-acryloyl N'-cyanoacetohydrazide (ACAH), were carried in dimethyl formamide in presence of azobisisobutyronitrile as initiator and kinetic studies on the polymerization behavior of ACAH, conducted. Complex formation of ACAH monomer and polymer (PACAH) with Cu(II) and Fe(II) cations was investigated and the stability constant determined. The rate of copolymerization of ACAH with some conventional monomers named vinyl acetate, methyl methacrylate, and acrylonitrile was measured as a function of mole fractions of comonomers. The reactivity ratios (r 1 , r 2 ) for the various investigated copolymer systems with the Q and e values of ACAH monomer were determined. The thermal gravimetric analysis of prepared polymer and copolymers with acrylonitrile was done.
