A polymer support is provided which comprises hydroxypolyC2-4 alkyleneoxy chains attached to a cross-linked polymer. The hydroxypolyC2-4 alkyleneoxy chain contains from 2 to 8 C2-4 alkyleneoxy groups and the polymer support has from about 0.1 to about meq free hydroxy groups per gram of polymer. Preferably, the cross-linked polymer is a copolymer comprising phenylethylene and 4-hydroxyphenylethylene units or phenylethylene and 4- chloromethylphenylethylene units.

L'invention concerne un support polymère comprenant des chaînes hydroxypolyC2-4 alkylèneoxy fixées à un polymère réticulé. La chaîne hydroxypolyC2-4 alkylèneoxy contient de 2 à 8 groupes C2-4 alkylèneoxy et le support polymère possède environ 0,1 à environ 5 mEq de groupes hydroxy libres par gramme de polymère. Le polymère réticulé est, de préférence, un copolymère comprenant des unités de phényléthylène et de 4-hydroxyphényléthylène ou des unités de phényléthylène et de 4-chlorométhylphényléthylène.
