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

Patent number: 7472584Abstract: The present invention is directed to an apparatus and a method for monitoring the viscoelastic properties, of a liquid film (e.g. coating). The apparatus includes a substrate for supporting a liquid film and a T-bar probe that is partially submerged in the liquid film. The apparatus is designed to be attached to a conventional rheometer equipped with a means for effecting relative movement between the probe and the substrate and means for monitoring the resistance to movement of the probe in contact or partially submerged in the film to obtain a measurement of the solidification properties of the liquid film. This apparatus and method are particularly useful in comparing the effects of film formers, viscosity modifiers, solvents, and minerals on the drying rate of coatings at the early stage of film formation.Type: GrantFiled: December 21, 2005Date of Patent: January 6, 2009Assignee: Eastman Chemical CompanyInventors: Kab Sik Seo, Jessica Dee Posey-Dowty
