英文摘要A novel alternate copolymer of poly(ether ether ketone), 50% PEDEK-PETMDEK was designed and synthesized successfully by aromatic nucleophilic substitution polycondensation. The structure of the alternate copolymer was determined by H-1 NMR. The properties of the 50% alternate copolymer, 50% random copolymer, homopolymer PEDEK and PETMDEK were studied by DSC and WAXD etc.. We found that solubilities and thermal properties of 50% alternate copolymer and 50% random copolymer were quite different, the former is amorphous, and could be easily dissolved in common organic solvents, while the latter is a semi-crystalline polymer and could not be dissolved in almost any solvents except concentrated H2SO4 just like the homopolymer PEDEK. The properties of 50% alternate copolymer are more like those of the homopolymer PETMDEK. The glass transition temperature of the 50% alternate copolymer is higher than that of the 50% random copolymer.
