Abstract
Abstract1‐Methyl‐1‐(3‐vinylphenylazo)ethyl acetate (1a), diphenyl‐(3‐vinylphenylazo)methyl acetate (1b), and α‐phenylazo‐α‐(4‐vinylphenyl)benzyl acetate (2) were prepared and copolymerized with styrene using AIBN as initiator at 50°C. The azo functions of the monomers remain unaltered during the polymerization process at this temperature. The resulting copolymers 3a, 3b, and 4 were used as initiators for the polymerization of methacrylonitrile (MAN). The grafted copolymers of styrene and MAN were separated from polystyrene and poly(methacrylonitrile). The different rates of polymerization of MAN, initiated by the azo group containing polymer 3b or 4 or by diphenylphenylazomethyl acetate, a low molecular model initiator, and the different molar masses obtained allow a discussion of the mechanism involved.
