Abstract: Nonisothermal melt crystallization kinetics of thio-ether-contained poly(ether ether ketone ketone) copolymers was studied by DSC. The result shows that the crystallization activation energy was increased accompanied by the introduction of thio-ether structure. The random copolymer possesses a higher crystallization activation energy than the block one at the same thio-ether ratio.

Key words: Poly(ether ether ketone ketone), Block copolymer, Random copolymer, Nonisothermal crystallization kinetics
