Telechelic poly(ether ketone)s were prepared by bulk polycondensations of 4'-fluoro-4-(trimethylsiloxy)benzophenone and 4'-fluoro-2-methyl-4-(trimethylsiloxy)benzophenone and by cocondensation with 4'-fluoro-4-(trimethylsiloxy)diphenyl sulfone. These A-B type monomers were cocondensed with activated aromatic difluoro compounds or a silylated diphenol containing a relatively thermostable aliphatic group (CH 2 or CH 3 ). This synthetic approach has the following three advantages ; first, the… CONTINUE READING
