Abstract: A separation module that includes a porous membrane, where the porous membrane includes a poly(phenylene ether) copolymer containing 10 to 40 mole percent repeat units derived from 2-methyl-6-phenylphenol and 60 to 90 mole percent repeat units derived from 2,6-dimethylphenol; and a block copolymer containing backbone or pendant blocks of poly(C2-4 alkylene oxide). The separation module can be used in devices for wastewater treatment, water purification, desalination, separating water-insoluble oil from oil-containing wastewater, membrane distillation, sugar purification, protein concentration, enzyme recovery, dialysis, liver dialysis, or blood oxygenation.

Abstract: An amphiphilic block copolymer comprises a poly(phenylene ether) block or a poly(phenylene ether) copolymer block and a hydrophilic block or graft. A method of making the amphiphilic block copolymer comprises polymerization of a hydrophilic ethylenically unsaturated monomer in the presence of poly(phenylene ether) or a poly(phenylene ether) copolymer to make the amphiphilic block copolymer. A porous asymmetric membrane comprises a poly(phenylene ether) or poly(phenylene ether) copolymer, and the amphiphilic block copolymer comprising a poly(phenylene ether) block or a poly(phenylene ether) copolymer block, and a hydrophilic block or graft. The porous asymmetric membrane is made by phase-inversion of a dope solution of the poly(phenylene ether) or poly(phenylene ether) copolymer and the amphiphilic block copolymer in a coagulation bath.

Abstract translation: 两亲嵌段共聚物包括聚（亚苯基醚）嵌段或聚（苯醚）共聚物嵌段和亲水嵌段或接枝。 制备两亲性嵌段共聚物的方法包括在聚（苯醚）或聚（苯醚）共聚物存在下聚合亲水性烯属不饱和单体以制备两亲性嵌段共聚物。 多孔不对称膜包括聚（亚苯基醚）或聚（苯醚）共聚物，以及包含聚（亚苯基醚）嵌段或聚（苯醚）共聚物嵌段的两亲性嵌段共聚物和亲水性嵌段或接枝。 多孔不对称膜是通过聚苯醚或聚苯醚共聚物的掺杂溶液和两亲性嵌段共聚物在凝固浴中进行相转化而制成的。
