Isothermal crystallization kinetics were investigated by differential scanning calorimetry (DSC) for poly(p‐phenylene sulfide) (PPS) doped with amorphous carbon or crystalline graphite particles. Both types of carbon forms have been found to affect the crystallization behavior of PPS to different extents. The crystalline graphite particles have a more pronounced effect on the overall rate as well as mechanisms of PPS crystallization than do the amorphous carbon particles. Relative contributions and competition from crystallizations of two different crystals in the later‐stage crystallization of PPS have been found to cause the phenomenon of deviation from linearity in the Avrami plots. A sequential crystallization model has been shown to describe well the crystallization behavior of the PPS doped with the particles. © 1995 John Wiley & Sons, Inc.
