Abstract
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 the organotin monomer were calculated.
