摘要：

A series of chain-extended poly(aryl ether ketones) (PAEKs) and poly(ether ketone ketone)/poly(ether ether ketone) (PEKK/PEEK) block copolymers have been prepared via the nucleophilic polycondensation and evaluated. The former were prepared by reacting a bisphenol, such as hydroquinone, with a series of difunctional PAEK oligomers, while the latter were prepared by reacting those same oligomers with a bisphenol, such as hydroquinone, and an activated dihalo compound, such as 4,4'-difluorobenzophenone. The chain-extended copolymers show good mechanical and thermal properties which can be varied by varying the particular bisphenol used and/or the oligomer molecular weight. The PEKK/PEEK block copolymers also have overall attractive properties; an in-depth evaluation of one particular polymer showed properties comparable to those of commercial poly(aryl ether ketones).
