SYNTHESIS AND MORPHOLOGICAL STRUCTURE OF POLY (PHENYLENE SULFIDE AMIDE)

Received Date: 7 December 1993

Poly (phenylene sulfide amide) (PPSA) has been synthesized by using sulfur as Ssource which reacts with dichlorobenzamide (DCBA) and alkali in polar organic solvent atthe atmospheric pressure. The polymer structures were determined by elemental analysis,FT-IR and 1H-NMR. It is shown that the yielded polymer has linear structure and itsstructure unit is -p-C6H4-CONH-p-C6H4-S-. The polymer morphology was studied byX-ray diffraction and polarized microscopy. The results show that PPSA is a crystalline polymer and its spherulites are the aggregation of nontwisting lamella or micro-thread structure.Under shearing force,these crystals are dispersed to form micro-dibrillar structure.The decomposition kinetics of PPSA was also studied at different heating rates.The decomposition energy of PPSA is higher than that of PPS.
