A process for attaching a polyethylene glycol compound to a macromolecule to prepare a conjugate or adduct between the polyethylene glycol compound and the macromolecule is described. The process comprises the steps of (1) preparing an activated PEG or an activated PEG derivative by incorporating an acrylic ester, an acrylic thioester or an acrylamido group into the PEG or PEG derivative; (2) reacting the activated PEG or PEG derivative with a macromolecular material comprising one or more sulphydryl groups, primary amino groups and/or secondary amino groups and (3) recovering the conjugate of the PEG or PEG derivative and the macromolecular material.

Abstract

A process for attaching a polyethylene glycol compound to a macromolecule to prepare a conjugate or adduct between the polyethylene glycol compound and the macromolecule is described. The process comprises the steps of (1) preparing an activated PEG or an activated PEG derivative by incorporating an acrylic ester, an acrylic thioester or an acrylamido group into the PEG or PEG derivative; (2) reacting the activated PEG or PEG derivative with a macromolecular material comprising one or more sulphydryl groups, primary amino groups and/or secondary amino groups and (3) recovering the conjugate of the PEG or PEG derivative and the macromolecular material.
