Summary Copolymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS, monomer 1) with 2-hydropropyl methacrylate (monomer 2) was conducted in pure water at 80°C. The reactivity ratios estimated from the compositional data of the copolymers at low conversion are r1=0.04±0.04 and r2=6.30±0.48, and values of Q1 and e1 are 0.16 and 1.37, respectively. Copolymer microstructure predicted by statistical calculation shows mean sequence length of MI shorter than 2. These results can be attributed to the strong repulsion between the ionized chain radical and charged monomer of AMPS.
