摘要：
Polyetherethersulphone-polyethersulphone copolymers have been brominated on the hydroquinone residue and these bromine groups replaced by phenylethynyl, trimethylsilylethynyl and 3-methylbutyn-2-olyl residues using organo-palladium catalysts. The latter two ethynyl species have been hydrolysed to give free ethynyl substituents on the polymer. Hydrolysis conditions are discussed, and some thermal properties of the modified polymers reported.
