Transformational behaviour of T_g and T_m for PEEKK-PEBEKK copolymers with various biphenyl content was studied by using DSC. Results revealed that the glass transition temperature T_g for the copolymers gradually increased with increasing biphenyl content n_B. The melting points T_m of the copolymers obviously depended on n_B. T_m value was minimum when n_B=0.35. Heat behaviour of the copolymers could be markedly changed by heat treatment. Behaviour of double melting peak for the copolymer resulted from the crystal melting and the recrystallization was also studied.
