A process for preparing a poly(aryl ether ketone) which consists essentially of reacting 4,4'-bis(p-fluorobenzoyl)diphenyl ether with 1,4-bis(p-hydroxybenzoyl)benzene under nucleophilic polycondensation conditions.
A process for preparing a poly(aryl ether ketone) which consists essentially of reacting 4,4'-bis(p-hydroxybenzoyl)diphenyl ether with 4,4'-bis(p-fluorobenzoyl)benzene under nucleophilic polycondensation conditions.
A process for preparing a poly(aryl ether ketone) which consists essentially of reacting 1,4-bis(4-fluorobenzoyl)benzene with 4-fluoro-4'-hydroxybenzophenone and 4,4'-dihydroxybenzophenone in a mole ratio of 1:1:1 under nucleophilic polycondensation conditions.
A process for preparing a poly(aryl ether ketone) which consists essentially of reacting 1,4-bis(p-fluorobenzoyl)benzene with 4,4'-difluorobenzophenone and 4,4-dihydroxybenzophenone in a mole ratio of 1:0.5:1.5 under nucleophilic polycondensation conditions.
A process for preparing a poly(aryl ether ketone) which consists essentially of reacting 1,4-bis(p-hydroxybenzoyl)benzene with 4,4'-difluorobenzophenone and 4,4'-dihydroxybenzophenone in a mole ratio of 1:1.5:0.5 under nucleophilic polycondensation conditions.
