Styrene (M1) has been copolymerized with 0-, m-and p-halostyrenes (M2) at temperatures between 40 and ll0~C, using azoisobutyronitrile as initiator; the halostyrenes were labelled with 14C in the fl-position. The compositions of the copolymers were determined by liquid scintillation counting. ## Si
The free-radical copolymerization of styrene with butyl acrylate was carried out in benzene and benzonitrile at 50ยฐC. Differences between the apparent reactivity ratios determined in this work and those previously reported in bulk indicated noticeable solvent effects. This is explained by a qualitat
## Abstract The true monomer reactivity ratios for the vinyl acetate/butyl acrylate system were determined with experimental data from the cumulative copolymer composition at low, intermediate, and high conversions and with the monomer partitioning among the aqueous, microemulsion droplet, and poly
