2-Hydroxyethyl methacrylate (HEMA) and styrene (S) have been copolymerized in a 3 mol ⅐ L Ϫ1 N,NЈ-dimethylformamide (DMF) solution using 2,2Јazobis (isobutyronitrile) (AIBN) as an initiator over a wide composition and conversion range. From low-conversion experiments and 1 H-NMR analysis, the monome
