Synthesis and characteristics of polyarylene ether sulfones
… Two different types of mechanical tests together with DSC and SEM measurements showed that improved solvent resistance (especially to liquids of interest to NASA for aerospace functions) could be achieved via a novel liquid induced crystallization process. ¹³C and proton NMR spectral …

Toughening of cyanate ester networks with reactive thermoplastic modifiers
… Bisphenol-A based amorphous poly(arylene ether)s have been successfully utilized to toughen the cyanate ester networks. Blends of reactive and non-reactive Bisphenol-A based amorphous poly(arylene ether sulfone)s were also demonstrated to be useful tougheners, apparently by allowing phase …
