摘要: Abstract Novel poly(arylene thioether)s were synthesised using the one pot polymerisation method from bis( N,N -dimethyl-S-carbamate) of 2,2-bis(4-mercaptophenyl)propane and activated difluoro aromatic compounds. Each polymers, obtained in good yields with fairly high molecular weights, characterised by IR, GPC NMR analyses. In particular, characterisation was performed 1 H NMR, 13 C DEPT, 2D COSY HSQC experiments. To study effect on thermal properties replacing ethereal oxygen atoms sulfur atoms, we have counterparts, ether)s, similar weights. We observed that substitution results a slightly lower stability for poly(thioether ketone)s, both under nitrogen air, does not modify T g values. For sulfone), other hand, is equal to poly(ether while 10 °C lower. Furthermore, each sample completely amorphous, exception ketone)s (sample 1b), which shows capacity crystallise, even if very slow crystallisation kinetics.
