MONOMERS CONTAINING POLYOXYALKYLENES AND POLYMER SUPPORTS THEREFROM

摘要

A process for the preparation of an oligonucleotide is provided. The process comprises the assembly of an oligonucleotide attached to a solid support, wherein the solid support is prepared by a process comprising polymerisation of a monomer which comprises a protected hydroxypolyC2-4 alkyleneoxy chain attached to a polymerisable unit wherein the protected hydroxypolyC2-4 alkyleneoxy chain contains from 2 to 10 C2-4 alkyleneoxy groups and wherein the hydroxypolyC2-4 alkyleneoxy chain is protected with an acid-labile protecting group, preferably an optionally substituted trityl group.
