Studies on Poly(ether ether ketone ketone)-Poly(ether biphenyl ether ketone ketone) Copolymers and Blends

Abstract

Abstract: We synthesized a series of polymers: poly(ether ether ketone ketone) (PEEKK),poly (ether biphenyl ether ketone ketone) (PEBEKK) and their copolymer by polycondensation.We also prepared a series of PEEKK-PEBEKKblends.By using DSCmethod, we found that T_g of the copolymers and the blends rose with the increasing of biphenyl contents in the polymers.T_c of the copolymers and the blends is higher than the corresponding homopolymer.From the results, we think that PEEKK-PEBEKKcopolymer and blends are miscible and the copolymer is random.

Key words: Poly(ether ether ketone ketone)-poly(ether biphenyl ether ketone ketone)copolymer, Blend, DSC
