Abstract
Poly(aryl ether ketone)s (PAEKs) based on 2-(3′-trifluoromethylphenyl) hydroquinone and 4,4′-difluorobenzophenone were synthesized and characterized in the presence or absence of 2,4′,6-trifluorobenzophenone (BB′2 monomer). The influence of the incorporation of a branched structure (BB′2 monomer) on the gas transport properties of PAEKs was investigated. The results showed that PAEKs with a branched structure possess a higher permeability and selectivity than PAEKs without a branched structure. Moreover, improvements in the permeability and selectivity were enhanced with increasing content of BB′2 monomer. This synergistic effect on permeability and selectivity was mainly due to the higher fractional free volume and the unique size and distribution of free volume holes arising from the incorporation of the branched structure. © 2013 Society of Chemical Industry
