Abstract
Poly (phenylene sulfide) (PPS) and its derivatives, poly (phenylene sulfide-co-phenylene ketone) (PPSK), poly(phenylene sulfide-co-phenylene ether) (PPSE), poly (biphenylene sulfide) (PBPS) and poly (phenylene sulfide-co-phenylene sulfone) (PPSS), were synthesized and their thermal properties were investigated by differential scanning calorimetry and thermogravimetric analysis. PPSK, PBPS and PPS show high crystallinity, in that descending order, while PPSS is totally amorphous. Semi- and non-crystalline PPS/PPSS polymers were melt blended. The blends showed relatively high miscibility and thermal stability. The T(g) of PPS/PPSS blends shows 10 and 45-degrees-C inward shift; the melt crystallization temperature (T(mc)) of PPS decreased to 227-degrees-C in the PPS/PPSS blend compared to 244-degrees-C for the PPS homopolymer, as determined by differential scanning calorimetry in a cooling scan.
