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 using 1
mol% azobisisobutyronitrile as initiator. The copolymer compositions were determined from
tin analyses. The monomer reactivity ratios for copolymerizations of ABTB (monomer-1) with
allyl methacrylate, N-vinyl pyrrolidone and vinyl acetate have been found to be r 1= 0.28, r
2= 0.89; r 1= 0.07; r 2= 0.40 and r 1= 0.92, r 2= 0.99, respectively. The Q and e values for ...
