The kinetics of nonisothermal crystallization has been studied for sulfonated syndiotactic polystyrene containing 1.60mol%, 3.05mol%and 4.41mol%sulfo groups, and pure syndiotactic polystyrene by means of differential scanning calorimetry at various cooling rates. The theory of Mandelkern and the method of Mo Zhishen for nonisothermal crystallization are used to analyze the DSC data. The results show that the crystallization behavior of SsPS exhibits considerable differences in comparison to the neat sample. The degree of crystallinity and the rate of crystallization are significantly lowered by the presence of sulfo groups. The noninteger Avrami exponents, between 2 and 3, for sPS and SsPS samples during nonisothermal crystallization procedure indicate that a mixture of nucleation and growth mechanisms are occurring.
