A terpolymer of α-Methylstyrene/Acrylonitrile/Methylmethacrylate(AMS/AN/MMA) is synthesized by emulsion method. The chemical structure of terpolymer is characterized by FTIR and the miscibility of the terpolymer and CPVC is investigated with DSC. The influence of monomer ratio, synthesis condition on the conversion ratio is studied. The mechanical and processing properties of blends of CPVC with the terpolymer are researched. The results indicate that CPVC shows good miscibility with the terpolymer. By mixing CPVC with the terpolymer, the process performance of CPVC is improved, and with the increasing mass fraction of AMS in the terpolymer, the Vicat soft point of CPVC increased gradually.
