  • Patent number: 9243072
    Abstract: 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: Grant

  • Publication number: 20100160454
    Abstract: Antimicrobial agents, products and compositions incorporating the agents, and methods of using the compositions and products are provided. The antimicrobial agents comprise 1,2-cyclohexanedimethanol, 1,4-cyclohexanedimethanol, 2,2,4,4-tetramethyl-1,3-cyclobutanediol, or mixtures thereof. These agents have surprisingly been found to inhibit microbial growth at a much lower concentration than other glycols with known antimicrobial activity.
