Abstract
The disclosure relates to a cured composition obtained by curing a curable polymer composition comprising: (a) at least one hydroxyl group containing compound selected from diols, triols, tetraols, polyols, polymeric polyols, and mixtures thereof; and (b) a sulfonated styrenic block copolymer (SSBC) containing a block A, a block B, and a block D. Each block A and D is resistant to sulfonation and the block B is susceptible to sulfonation having a degree of sulfonation of >10 mole %. The curable polymer composition is cured by treating with radiation or thermal energy for improved mechanical properties. The cured composition can be used as a membrane in water purification applications.
