DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 52 Polyether-polysulfone compns. have been discovered which incorporate structural subunits derived from sulfonated bis(halophenyl) sulfones, dihydroxyterphenyls, and/or bis(hydroxyphenyl)pyridines. The sulfonated polyether-polysulfones are useful as materials for use in polymer electrolyte membranes (PEMs) in fuel cells owing to their high proton conductivities (0.There are some reagents like 36603-49-3 is used in this study.02-0.07 S/cm at 20° C. 36603-49-3 is the cas registry number of certain chemical which is used as reagents here. and 100 percent humidity). A typical polymer was manufd. by polymn. of 5.482 g 4,4''-dihydroxy-m-terphenyl with 2.126 g 4,4'-difluorodiphenyl sulfone and 5.747 g 4,4'-difluoro-3,3'-disodiosulfodiphenyl sulfone in a NMP-PhMe mixt. contg.
