The present disclosure provides a bifunctional linker for coupling at least one functional moiety, preferably a bis-allyl propionic acid (BAPA), to a polymer-containing matrix. Also disclosed by the present disclosure are anhydrides of the bifunctional linker, processes for preparing the bifunctional linker and such anhydride, as well as surfaces, such as cellulose containing matrices, coupled with the bifunctional linker, at times, the latter carrying a functional agent.

Methods for the cross-metathesis of polysaccharides with one or more olefin-terminated side chains and cross-metathesized products are described. In an exemplary embodiment, a method for the synthesis of cellulose -carboxyesters via olefin cross-metathesis is described. Conditions of the reactions were relatively mild and the olefin-substituted polysaccharides and the appropriate monomeric olefin partners appear to follow Grubbs rules as summarized herein. The compounds and methods may be useful for structure-property studies, particularly those aimed at developing polymers for drug delivery, such as for controlled-release drug delivery systems, controlled-release coatings, increasing bioavailability of drugs, and maintaining drug supersaturation in the GI tract.

A process for preparing a consumer product including a chemically modified polysaccharide, where the process includes the steps of combining a slurry including polysaccharide with a reactant to form a polysaccharide-reactant mixture, where the reactant includes an ester group; combining a base with the polysaccharide-reactant mixture to form a polysaccharide-reactant-base mixture; and allowing the polysaccharide-reactant-base mixture to form a transesterified polysaccharide mixture, where the transesterified polysaccharide mixture includes an alcohol.
