Organotin polymers: 6. Copolymerization parameters for tri-n-butyltin maleate, acrylate and methacrylate with some vinyl monomers

The monomer reactivity ratios for the copolymerization of methyl methacrylate (M 1), styrene (M 1), butyl acrylate (M 1) and acrylamide (M 1) with tri-n-butyltin maleate (M 2) have been found to be r 1 = 15.40, r 2 = 0.01; r 1 = 6.70, r 2 = 0.05; r 1 = 9.39, r 2 = 0.11; and r 1 = 122.44, r 2 = 0.06,...

Description
Summary:The monomer reactivity ratios for the copolymerization of methyl methacrylate (M 1), styrene (M 1), butyl acrylate (M 1) and acrylamide (M 1) with tri-n-butyltin maleate (M 2) have been found to be r 1 = 15.40, r 2 = 0.01; r 1 = 6.70, r 2 = 0.05; r 1 = 9.39, r 2 = 0.11; and r 1 = 122.44, r 2 = 0.06, respectively. Also, the copolymerization parameters of acrylamide (M 1) with tri-n-butyltin acrylate (M 2) or methacrylate (M 2) were as follows: r 1 = 0.11, r 2 = 0.82; and r 1 = 1.46, r 2 = 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.
