STUDY ON THE SYNTHESIS AND PROPERTY DIFFERENCES OF 2 KINDS OF TERMINATED POLY(PHENYLENE SULFIDE) OLIGOMERS

Chloro terminated poly(phenylene sulfide) (PPS) oligomers and mercapto terminated PPS oligomers have been synthesized separately by changing the molar ratio of p-dichlorobenzene and sodium sulfide, and characte rized by FT-IR spectroscopy, Raman spectroscopy, X-ray diffraction and thermogravimetric analysis. The effects of terminal groups upon the o ligomer's structure and properties have also been studied. The results show that the PPS oligomers with terminal chloro groups have a higher molecular weight, more crystallinity and better thermal stability com pared with PPS oligomers with terminal mercapto groups.
