VERFAHREN ZUR HERSTELLUNG VON POLYETHERBLOCKCOPOLYSULFONEN

Polyether blocked copolymer sulfones (PEBSU) can be prepared by reaction with OH-functional polyethers, e.g. by reaction of an aromatic sulfone polymer (A) with an aliphatic polyether with on average at least one, e.g. two terminal OH group (B).
