Abstract

The results of crystallization and melting studies of polyphenylene sulfide (PPS) in presence of a low molecular weight (LMW) compound ate reported. The crystallization is studied using differential scanning calorimetry (DSC) and optical microscopy. It is observed that the addition of the LMW compound resulted in a decrease in melting point and crystallization temperature, suggesting significant changes in crystalline morphology and crystallization behavior, respectively. The spherulitic morphology was also found to become altered in terms of size and texture, confirming incorporation of the compound in the structure. The changes observed were more significant for melt-blended samples than those observed for dry blends.
