| 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-PEBEKK blends. By using DSC method, 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-PEBEKK copolymer and blends are miscible and the copolymer is random. |
