In one aspect, the disclosure relates to the production of alternating polymers of maleic anhydride or an N-substituted maleimide with a stilbene.

Alternating copolymers of selected unsymmetrically substituted stilbenes and maleic anhydride or N-substituted maleimides

Described herein are block copolymers that can be used as compatibilizers. The block copolymers can be graft block or triblock copolymers. The block copolymers can include a polysaccharide or a polyester and a polyolefin. Also described herein are polymer blends that can include and be made using the block copolymers described herein.

Copolymer compatibilizers and uses thereof

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 &#x3c9;-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.
