Patent number: 9783676Abstract: An antimicrobial polyurethane foam that is formed from: a multi-functional isocyanate component; an aqueous polyol component reactive with the multi-functional isocyanate component; an antimicrobial metallic compound; and a complexing agent. The complexing agent is used to form a stable blend of the antimicrobial metallic compound with the polyol component. Exemplary complexing agents include amine compounds, ammonium-containing compounds, and ammonia as well as combinations of these compounds. The antimicrobial metallic compound can be a silver, zinc, or copper compound. Desirably, the antimicrobial metallic compound is silver saccharinate. A process of making the antimicrobial polyurethane foam and stable blends used in the manufacture of the antimicrobial polyurethane foam are also disclosed.Type: GrantFiled: November 11, 2015Date of Patent: October 10, 2017Assignee: Avent, Inc.Inventors: Bhalchandra Karandikar, Bruce L. Gibbins

Patent number: 5236667Abstract: A method of chemically modifying the poly (methyl methacrylate) (hereinafter "PMMA") clad surface of an optical fiber to introduce amino groups. N-butyl lithium in a suitable organic solvent with ethylene diamine is applied to the clad surface of the optical fiber in a substantially oxygen-free atmosphere, such as nitrogen, at approximately 10.degree. C. to 40.degree. C. for about one to two hours. A pH-sensitive dye with isothiocyanate functionality can be bounded to the modified clad surface resulting in a pH sensor based on fiber optics.Type: GrantFiled: June 25, 1991Date of Patent: August 17, 1993Assignee: University of PittsburghInventors: Jules B. Puschett, Krzysztof Matyjaszewski, Bhalchandra Karandikar
