The copolymer derived from the copolymerization in high capacity kettle were testified that copolymerization between AN and MMA occurred. The microcapsules in the films are distributed in the copolymer film matrix. The heat-absorbing temperatures and heat-evolving temperatures of the films are almost the same as that of the MOCT, respectively. In addition, the enthalpy efficiency of MOCT, the melting enthalpy and the crystallizing enthalpy rises with the contents of MOCT increasing.The decomposition temperature of copolymers in the films containing various contents of MOCT decreases with the contents of MOCT increasing.
