Abstract: The invention relates to a poly(aryl ether sulfone) (PAES) copolymer (P2) with ionically and/or covalently attached bioactive compound(s), articles comprising (P2), methods of making (P2), and methods for making articles such as membranes comprising (P2). Functionalized side-chain PAES copolymers (P1) permit the immobilization of a bioactive compound on copolymer's functionalized side chains for preparing bioactive articles. In particular, an antithrombotic agent such as heparin may be immobilized to form a bioactive membrane structure suitable for hemodialysis to avoid or eliminate the injection of such antithrombotic agent to a patient undergoing hemodialysis. Preferred embodiments include heparinized PAES copolymers and membranes comprising them.

Abstract: A process for the manufacture of a polyarylethersulfone “PAES” (P2) using recycled polymeric material, comprising heating a reaction medium (RM) comprising a recycled polymeric material containing a polyarylethersulfone “PAES” (P1), at least one monomer (M), an alkali salt-forming agent (A) and a polar aprotic solvent (S) to reach a reaction temperature of at least 150° C. to form a PAES (P2); and separating the forned PAES (P2) from the reaction medium. The PAES (P1) recycle ratio may be from 100 wt. % to 1 wt. %. The recycled polymeric material added to the reaction medium may further include other polymer(s), solid fillers, and/or additives. The monomer (M) may be at least one aromatic diol monomer (AA) and/or at least one aromatic dihalo monomer (BB). The diol (AA) may comprise bisphenol A, bisphenol S, biphenol, a 1,4:3,6-dianhydrohexitol sugar diol and/or tetramethyl bisphenol F, and the dihalo (BB) may comprise non-sulfonated and/or disulfonated dihalodiphenylsulfone.
