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: 5705631Abstract: A laminar flow process for preparing cellulose diacetate fibers is disclosed. In the process, a precipitation-acid stream and an acid-dope stream are contacted in a zone having substantially laminar flow. The acid-dope stream is annularly disposed within and flows in the same direction as the precipitation-acid stream. The precipitation-acid stream has a temperature of 100.degree. to 200.degree. F. and comprises 25 to 35 percent by weight acetic acid and 75 to 65 percent by weight water. The acid-dope stream has a temperature in the range of 100.degree. to 200.degree. F. and comprised of 5 to 22 weight percent of cellulose diacetate having an inherent viscosity of at least 1.0, and 95 to 78 percent by weight of a mixture comprising 65 to 90 weight percent acetic acid and 35 to 10 weight percent water. The precipitation-acid stream has a linear flow greater than or equal to the linear flow of the acid-dope stream. The weight ratio of the precipitation-acid stream to the acid-dope stream is at least 9:1.Type: GrantFiled: December 15, 1995Date of Patent: January 6, 1998Assignee: Eastman Chemical CompanyInventor: Michael Orlando Malcolm
