Abstract
The results of crystallization and melting studies of polyphenylene su lfide (PPS) in presence of a low molecular weight (LMW) compound are r eported. The crystallization is studied using differential scanning ca lorimetry (DSC) and optical microscopy. It is observed that the additi on of the LMW compound resulted in a decrease in melting point and cry stallization temperature, suggesting significant changes in crystallin e morphology and crystallization behavior, respectively. The spherulit ic morphology was also found to become altered in terms of size and te xture, confirming incorporation of the compound in the structure. The changes observed were more significant for melt-blended samples than t hose observed for dry blends.
