Dr. Webster – Professor and Chair of NDSU’s Coatings and Polymeric Materials department, and CSMS faculty researcher – received the patent on November 30, 2018 following a roundtable hosted by Senator John Hoeven.

The roundtable brought together Andrei Iancu, Director of the U.S. Patent and Trademark Office (USPTO), and local researchers and business leaders. Dr. Hoeven organized the meeting to give Iancu firsthand knowledge about the needs of North Dakota’s entrepreneurs and businesses in protecting their intellectual property.

The inventors for the patent, Biobased cyclic carbonate functional resins and polyurethane thermosets therefrom, include:

  • Dr. Webster
  • Previous CSMS participant James Docken, Jr. (as a graduate student)
  • Previous CSMS participant Satyabrata Samanta (as a Postdoctoral researcher)
  • James Bahr (Senior Research Engineer with NDSU’s Research and Creative Activity).

ABSTRACT:
The invention relates to a resin having a plurality of cyclic carbonate groups comprising the reaction product of: a) an epoxidized sucrose fatty acid ester resin, and b) carbon dioxide where a) and b) are reacted under conditions sufficient to carbonylate a plurality of the oxirane groups of the epoxidized sucrose fatty acid ester resin, and optionally in the presence of a catalyst or of a solvent. In one embodiment the epoxidized sucrose fatty acid ester resin is epoxidized sucrose soyate. The invention also relates to methods for producing a resin having a plurality of cyclic carbonate groups. In a method of the invention, an epoxidized sucrose fatty acid ester resin is contacted with carbon dioxide under conditions sufficient to carbonylate a plurality of the oxirane groups of the epoxidized sucrose fatty acid ester resin, and optionally in the presence of a catalyst or of a solvent. Other embodiments of the invention relate to curable composition containing a) a resin having a plurality of cyclic carbonate groups; b) an alkyl amine curing agent having two or more reactive amine groups; and c) optionally, a catalyst; and cured compositions and articles.

Congratulations again to Dr. Webster and his CSMS research group!
