摘要：
The radical copolymerization of 2-hydroxyethyl methacrylate (HEMA) and lauryl methacrylate was investigated at 60 degree C with alpha , alpha prime -azobisisobutyronitrile in benzene, tetrahydrofuran, tert-butylalcohol, and dimethylformamide. HEMA was found to have an abnormally high, apparent monomer reactivity ratio in benzene, corresponding to its high aggregation tendency in this solvent as a result of hydrogen-bonding. The apparent reactivity ratios are more or less close to azeotropic unity in the other solvents. The solution behavior of monomers is proposed as a factor in the copolymerization between hydrophilic and hydrophobic monomers.
