Polyether ether ketone and polyether ether ketone copolymers were prepared by the nucleophilic substitution reaction of 4,4′-difluorobenzophenone with hydroquinone and with varying mole proportions of hydroquinone and methyl hydroquinone using sulfolane solvent in the presence of anhydrous K 2 CO 3 . The polymers were characterised by different physico-chemical techniques. The crystallinity...
Polyether nitrile and polyether nitrile copolymers with pendant methyl groups were prepared by the nucleophilic substitution reaction of 2,6 ' -dichlorobenzonitrile with hydroquinone (HQ) and with varying mole proportions of HQ and methyl hydroquinone (MeHQ) using N-methyl pyrrolidone solvent in the presence of anhydrous K 2 CO 3 . The polymers were characterised by different...
