Abstract

See full text

This invention provides a method of preparing a polymeric delivery system for active ingredients. The delivery system is formed either by attaching the active ingredient to a linker through a hydrolyzable covalent bond, then forming a covalent bond between the linker and a portion of the subunits of a cross-linked polymer, or by attaching a linker to a portion of the subunits of a cross-linked polymer, then attaching the active ingredient to the polymer-linker combination through a hydrolyzable covalent bond. The invention also provides a delivery system comprising an active ingredient covalently bonded through a hydrolyzale covalent bond to a linker, which is in turn covalently bonded to a portion of subunits of a cross-linked polymer.
