Abstract
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 5 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.
