Patent number: 9243072Abstract: This invention provides cellulose ester interpolymers, and methods of oxidizing cellulose interpolymers and cellulose ester interpolymers. The invention also provides routes to access carboxylated cellulose ester derivatives with high acid numbers wherein the carboxyl group is attached directly to the cellulose backbone by a carbon-carbon bond. Through functionalization of an intermediate aldehyde, the corresponding cationic or zwitterionic cellulose ester derivatives can also be accessed. The interpolymers of the present invention have a number of end-use applications, for example, as binder resins in various types of coating compositions and as drug delivery agents.Type: GrantFiled: December 27, 2012Date of Patent: January 26, 2016Assignee: Eastman Chemical CompanyInventors: Charles Michael Buchanan, Norma Lindsey Buchanan, Susan Northrop Carty, Chung-Ming Kuo, Juanelle Little Lambert, Michael Orlando Malcolm, Jessica Dee Posey-Dowty, Thelma Lee Watterson, Matthew Davie Wood, Margaretha Soderqvist Lindblad
