The effects of solvent and concentration in the radical copolymerization of styrene (ST) and methacrylic acid (MAA) on the nature of intramolecular hydrogen bonding in the prepared copolymers were investigated. The copolymerizations at lower monomer concentration in benzene gave copolymers with exceedingly higher intramolecular association ability compared to the copolymerizations in dioxane and at higher monomer concentration in benzene. This result could be explained, assuming an intrachain reaction of the end radical with MAA monomers hydrogen‐bonded to MAA segments in the macroradical.
