Patent number: 7439289Abstract: Benzoylresorcinol-based phosphate esters are obtained by reacting a benzoylresorcinol compound with a chlorophosphate. The benzoylresorcinol-based phosphate esters can function as flame retardants and/or UV stabilizers for polycarbonates (PC), poly(phenylene oxide) (PPO), polyesters (e.g., PET and PBT), polycarbonate and acrylonitrile-butadiene-styrene terpolymer (PC/ABS) blends, poly(phenylene oxide) and high-impact polystyrene (PPO/HIPS) blends and other polymers. The benzoylresorcinol-based phosphate ester flame retardants may possess enhanced thermal stability compared to resorcinol based phosphate ester (RDP). Synthetic procedures and applications of the benzoylresorcinol-based phosphate esters compounds are provided.Type: GrantFiled: September 21, 2005Date of Patent: October 21, 2008Assignee: Indspec Chemical CorporationInventors: Raj B.

Publication number: 20080206829Abstract: The present invention provides a polymer membrane enhanced with cured epoxy resin for use as the outer membrane of biosensors. The membrane includes approximately 30-80% epoxy resin adhesives, 10-60% polymer such as poly(vinyl chloride), polycarbonate and polyurethane and 0-30% plasticizers and 5-15% surface modifier reagent such as polyethylene oxide-containing block copolymers. Utilizing the polymer membrane of the present invention, a three-layered sensing element has been developed. This sensing element will be particularly useful for miniaturized biosensors used for in vitro blood measurements or for continuous in vivo monitoring such as implantable biosensors. This element includes an enzyme layer, an interference-eliminating layer and the novel polymer member of the present invention as the outer polymer layer. This novel sensing element shows excellent response characteristics in solutions and has an extremely long lifetime.Type: ApplicationFiled: January 17, 2008Publication date: August 28, 2008Applicant: UNIVERSITY OF SOUTH FLORIDAInventors: Bazhang Yu, Francis Moussy
