PPR were prepared with supported β-nucleating agent in this paper
the isothermal crystallization behavior and melting characteristics of PPR and β-PPR were studied with Differential Scanning Calorimeter (DSC). The isothermal crystallization kinetics of PPR and β-PPR were examined by Avrami model. It is indicated that the addition of supported β-nucleating agent improve the crystallization rate of PPR apparently and shorten the half crystallization time. Furthermore
the isothermal crystallization behavior of β-PPR depend little on the crystallization temperature and it mainly formed β-crystal. It is apt to form β-crystal for PPR when crystallization at low temperature.
