摘要
Poly(ether ketone ether ketone ketone) containing meta phenylene linkage(PEKEKmK) was synthesized from 4,4′ diphenoxybenzophenone and isophthaolyl chloride by electrophilic polycondensation and characterized by IR, DSC, TGA and WAXD. The crystallization of the PEKEKmK has been carried out under different conditions: melt crystallization, cold crystallization and solvent induced crystallization and the following order of crystallinity was obtained: W cx,melt > W cx,cold > W cx,sic .
