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 Tg of the copolymers and the blends rose with the increasing of biphenyl contents in the polymers.Tc 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
