Abstract: The present disclosure provides a porous membrane made of pentablock copolymer. The porous membrane includes an ABCBA block copolymer and has a number of pores. The A block is immiscible with each of the B block and the C block, the B block has a glass transition temperature (Tg) of 90 degrees Celsius or greater, and the C block has a Tg of 25 degrees Celsius or less. The A block comprises a poly(alkylene oxide), a substituted epoxide, a polylactam, or a substituted carbonate; B block comprises a vinyl aromatic monomer or a polyalkylmethacrylate and C block comprises a polyacrylate, a polysiloxane or a polyisoprene. A method of making a porous membrane is also provided. The method includes forming a film or a hollow fiber from a solution including a solvent and solids containing an ABCBA block copolymer. The method further includes removing at least a portion of the solvent from the film or the hollow fiber and contacting the film or the hollow fiber with a nonsolvent.

Abstract: Polycarbonate polymers comprising non-aromatic cyclic groups bonded with carbonate linking groups are described. A portion of the non-aromatic cyclic groups comprise a substituent having siloxane repeat units. Representative formulas of the substituents having siloxane repeat units include —CH2—CH2—Si(R4)2—(OSi(R4)2—R5, and —CH[Si(R4)2—(OSi(R4)2)m—R5]—CH3; wherein m is the number of siloxane repeat units; and R4 and R5 are independently alkyl, aryl, aralkyl or aralkylene. The polycarbonate polymer C typically comprises a high concentration of carbonate linking group, for example in an amount of at least 85 or 90 mol % or greater N based on the total linking groups of the polymer. Also described are compositions comprising the polycarbonate polymer and methods of making.
