Manufacturing techniques were modified and optimized for preparing composite films of sulfonated P3O polyphenylene oxide. Polymer ion exchange capacity IEC was coated onto promising porous substrate materials using a meniscus coating technique. Composite films of the 1.5 IEC polymer on Celgard KKX-2 porous polypropylene appeared to offer the most promise for meeting the contract requirements of 10 gsfd flux and 90 acid rejection of a feed containing 0.2 H2SO4 and 0.1 HNO3. Three trial spiral wound modules were fabricated. The modules were evaluated. Manufacturing procedures were developed to prepare tighter composite films of S-P3O on Celgard KKX-2 porous polypropylene. It is suggested that the meniscus coating technique be extended to development of composite films of S-P3O on laminated porous polysulfone dacron sailcloth backing. Practical casting solvent systems compatible with polysulfone have been developed. Modified author abstract
