Abstract

The present invention relates to novel co-polymers and their use in the manufacture of porous membranes for haemodialysis application. In particular, such a co-polymer comprises a first segment comprising recurring units poly(aryl ether sulfone) [PAES recurring units], and a second segment comprising-recurring units poly(vinyl pyrrolidone) [PVP recurring units], wherein said first segment and said second segment are linked together via a group of formula —O-Ph-NH—C(═O)—C(CH)—CH—.
