✦ Synopsis

Akstract--Radical copolymerizations of p-acryloyloxy-tri-n-butyltin benzoate (ABTB) with allyl methacrylate, N-vinyl pyrrolidone and vinyl acetate were carried out in solution at 70 ' 4 using I mol% azobisisobutyronitrile as initiator. The copolymer compositions were determined from tin analyses. The monomer reactivity ratios for copolymerizations of ABTB (monomer-l) with allyl methacrylate, N-vinyl pyrrolidone and vinyl acetate have been found to be r~ = 0.28, r 2 = 0.89; r I = 0.07; r 2 = 0.40 and r~ = 0.92, r 2 = 0.99, respectively. The Q and e values for the organotin monomer were calculated.

Abstraet--p-Acryloyloxybenzoic acid (ABA) and N-methacryloyloxytetrabromophthalimide (NMTP) were prepared. The monomer reactivity ratios for the copolymerization of tri-n-butyltin acrylate (monomer-l) with ABA and NMTP have been found to be r I = 1.01, r2 =0.40 and r I =0.69, r2 = 0.90 respectively;
