Abstract: Polvetheretherketone/polyethersulfone block copolymers were prepared by condensation of two oligomers and their dynamic mechanical behaviour were investigated.Two ditstinct relaxation peaks i.e.βand α',were observed in amorphous copolymer samples and it was found that the α' relaxation can be attributed to low temperature crystallization of PEEK.

Key words: PEEK/PES block copolymer, Dynamic mechanical behaviour, Transition behaviour
