Abstract

Abstract: The blends of polyether-ether ketone with cardo group (PEK-C) with polyphenylene sulfide (PPS) were prepared by melt-blending. The miscibility and crystalline properties of PEK-C/PPS blends have been investigated by DSC, WAXD and DMA. PEK-C was found to be immiscible with PPS. The cryrtallization temperatures of blends were 5～10℃ lower than that of the pure PPS. The degree of crystallinity of PPS in the blends increased with the increase of PEK-C content, which does not affect the unit cell parameter of PPS.

Key words: polyether-ether ketone with cardo group, polyphenylene sulifde, miscibility, crystallization behaviour
