Patent ID: 7956135

Claim:
A process for the manufacture of a molding, which comprises crosslinking an amphiphilic block copolymer of formula (1) in a mold wherein A is a hydrophobic polysiloxane or perfluoroalkyl polyether segment; B is a surface-modifying hydrophilic segment having a weight average molecular weight of ≧100 that is devoid of a crosslinkable group, wherein (a) B is a non-ionic segment selected from the group consisting of polysaccharide, polypeptide, poly(vinylpyrrolidone), polyhydroxyalkylacrylate, polyhydroxyalkylmethacrylate, polyacyl alkylene imine, polyacrylamide, polyvinyl alcohol, polyvinyl ether and a polyol; or (b) B is a polyionic segment selected from the group consisting of a polyallylammonium, polyethyleneimine, polyvinylbenzyltrimethylammonium, polyaniline, sulfonated polyaniline, polypyrrole, polypyridinium segment, a polyacrylic, polymethacrylic acid, a polythiophene-acetic acid, a polystyrenesulfonic acid, a zwitterionic segment, and a salt thereof; Q is a moiety comprising at least one crosslinkable ethylenically unsaturated group; (alk) is C 2 -C 20 -alkylene which is unsubstituted or substituted by hydroxy; L 1 , L 2 and L 3 are each independently of the other a linking group; p1 and q1 are each independently of the other an integer from 1 to 12; and either t is 0 and p and q are each independently of the other an integer from 1 to 25; or t is an integer from 1 to 8 and p and q are each 0.
