AbstractThe copolymerization parameters of 2‐acryloyoxybenzoic (AOB) and 2‐methacryloyloxybenzoic (MOB) acids, methyl 2‐methacryloyloxybenzoate (MMOB), andN‐methyl‐N‐phenyl‐2‐aminoethyl methacrylate (MPAM) with styrene in benzene solution were determined and used in the calculation of the Alfrey‐Price copolymerization constantseandQfor AOB, MOB, MMOB, and MPAM. UsingeQthus determined and the corresponding tabulated values for methacrylic acid (MAA), the copolymerization parameters of pairs AOB‐MPAM, MOB‐MPAM, MMOB‐MPAM, and MAA‐MPAM were calculated. They are compared with those determined by the copolymerization of these pairs in which the interaction of functional groups o
