The monomer reactivity ratios for the copolymerization of methyl methacrylate (M1), styrene (M1), butyl acrylate (M1) and acrylamide (M1) with tri-n-butyltin maleate (M2) have been found to be r1 = 15.40, r2 = 0.01; r1 = 6.70, r2 = 0.05; r1 = 9.39, r2 = 0.11; and r1 = 122.44, r2 = 0.06, respectively. Also, the copolymerization parameters of acrylamide (M1) with tri-n-butyltin acrylate (M2) or methacrylate (M2) were as follows: r1 = 0.11, r2 = 0.82; and r1 = 1.46, r2 = 0.85, respectively. The Q and e values for the organotin monomers (tri-n-butyltin maleate, acrylate and methacrylate) were calculated from the monomer reactivity ratios determined in the present and previous studies. Copolymerization reactions were carried out in solution at 70°C using 1 mol% AIBN, and the copolymer compositions were determined by tin analysis. The structure of the tri-n-butyltin maleate and the prepared copolymers was investigated by i.r. spectroscopy.
