Abstract

This invention describes the use of resveratrol and curcumin, representatives of naturally occurring polyphenols, in their native form, after hydrogenation, and as their respective allyl derivatives, individually, in combination with themselves and other commercial monomers, to make representative varieties of polymers, e.g., polycarbonates (PC), polyurethanes (PU), co-polymers and biodegradable polymers.

Claims (10)

1. A synthetic polymer comprising at least one monomer unit of at least one naturally occurring plant polyphenol or a derivative thereof.

2. The synthetic polymer of claim 1 , wherein at least one chemical linkage of the polymer is carbonate, ether, carbamate, urethanes, thiocarbamate, thioether, or ester.

3. The synthetic polymer of claim 1 wherein the polymer is a homopolymer, co-polymer, block polymer, block co-polymer, grafted polymer, 3D polymer or interpenetrating polymer.

4. The synthetic polymer of claim 1 , wherein at least one naturally occurring plant polyphenol is Curcumin, a hydrogenated curcumin (Tetrahydrocurcumin), Resveratrol, or hydrogenated Resveratrol (DH-Resveratrol).

5. A derivative of a plant polyphenol selected from the group consisting of Curcumin diallyl carbonate, Tetrahydrocurcumin diallyl carbonate, Resveratrol triallyl carbonate, Mono-O-allyl curcumin, Tetra-allyl curcumin, Di-allyl Tetrahydrocurcumin, Tetra-allyl Tetrahydrocurcumin, and Tri-O-allyl resveratrol.

6. A synthetic polymer comprising at least one monomer unit of a polyphenol derivative of claim 5 .

7. The synthetic polymer of claim 6 , wherein at least one chemical linkage of the polymer is carbonate, ether, carbamate, urethanes, thiocarbamate, thioether, or ester.

8. A method of making at least one derivative of a plant polyphenol of claim 5 .

9. A method of making the synthetic polymer of claim 1 .

10. A method of making the synthetic polymer of claim 6 .
