CA 2482945
A polymer support is provided which comprises protected hydroxypolyC2-4 alkyleneoxy chains attached to a cross-linked polymer wherein the protected hydroxypolyC2-4 alkyleneoxy chain contains from 2 to 10 C2-4 alkyleneoxy groups and wherein the hydroxypolyC2-4 alkyleneoxy chains are protected with an acid labile group. The acid labile protecting group is preferably a poly- aryl methane protecting group. A monomer and process for the preparation of said support are also provided.
L'invention concerne un support polymère comprenant des chaînes protégées d'hydroxypoly C¿2-4? aklylène-oxy, fixées à un polymère réticulé, ladite chaîne hydroxypoly C¿2-4? alkylène-oxy contenant de 2 à 10 groupes d'alkylène-oxy C¿2-4?. Lesdites chaînes hydroxypoly C¿2-4? alkylène-oxy sont protégées par un groupe labile acide. Ledit groupe de protection labile acide est de préférence un groupe de protection méthane polyaryle. L'invention concerne également un monomère et un procédé de préparation dudit support.
