Polymerization behavior of acrylonitrile (AN) and methylacrylate (MA) was investigated in homogeneous melt phase. It was found that homogeneous melted mixture of polyacrylonitrile, acrylonitrile, and water could be prepared through the polymerization of AN and MA in water (monomer/water=80/20) at conversion over 80%. Reactivity ratio of the polymerization showed that higher alternating tendency and closer composition with monomer mixture than those in bulk and dispersion polymerization.
