## Abstract Frontal copolymerization is a process in which a spatially localized reaction zone propagates into a mixture of two monomers, converting them into a copolymer. In the simplest case of freeβradical copolymerization, a mixture of monomers and initiator is placed into a test tube. Reaction
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 50Β°C. 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
