The radical copolymerizations of p-cresyl acrylate, p-chlorophenyl acrylate, p-bromophenyl acrylate and m-nitrophenyl acrylate with methyl methacrylate have been studied. The reactivity ratios for these systems have been determined for copolymerization at 60 ° in benzene; they were calculated by the
Previously published material on the ␣-methyl styrene/methyl methacrylate (␣-MS/MMA) copolymer system at temperatures above the ceiling temperature of ␣-MS has focused on low-conversion results. Several attempts have been made to estimate copolymer reactivity ratios from experimental data, but in mo
## Abstract From a phenomenological point of view, the Mayo‐Lewis terminal model can describe both copolymer composition and the variation of copolymerization rate for the ethyl α‐benzoyloxymethylacrylate/methyl methacrylate/benzene/2,2′‐azoisobutyronitrile system.
## Abstract The terminal and penultimate model reactivity ratios in the free‐radical copolymerization of styrene and methyl methacrylate in bulk at 40°C were calculated by means of the simplex and scanning methods. Calculations showed that for the terminal model __r__~1~ and __r__~2~ vary in compar
