Publication number: 20080131393Abstract: The present invention relates to a block polymeric material. Typically the block polymer comprises units capable of having an average cationic charge density of about 15 or less, preferably 5 or less, more preferably from about 0.05 to about 5, even more preferably from about 0.05 to about 2.77, even more preferably from about 0.1 to about 2.75, most preferably from about 0.75 to about 2.25 units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for personal care products such as soaps and shampoos. The compositions have increased effectiveness for preventing re-deposition of grease during hand and body washing. The polymers are also effective as a soil release agent in fabric cleaning compositions.Type: ApplicationFiled: December 28, 2007Publication date: June 5, 2008Applicant: Rhodia Inc.Inventors: Dominic Wai-Kwing YEUNG, Vance Bergeron, Jean-Francois Bodet, Mark Robert Sivik, Bernard William Kluesener, William Michael Scheper

Patent number: 7365141Abstract: Optical devices fabricated from solvent processible polymers suffer from susceptibility to solvents and morphological changes. A semiconductive polymer capable of luminescence in an optical device is provided. The polymer comprises a luminescent film-forming solvent processible polymer which contains cross-linking so as to increase its molar mass and to resist solvent dissolution, the cross-linking being such that the polymer retains semiconductive and luminescent properties.Type: GrantFiled: March 13, 2006Date of Patent: April 29, 2008Assignee: Cambridge Display Technology Ltd.Inventors: Andrew Bruce Holmes, Xiao-Chang Li, Stephen Carl Moratti, Kenneth Andrew Murray, Richard Henry Friend

Patent number: 7358314Abstract: An insulation composition that comprises at least one nitrile butadiene rubber (“NBR”) having an acrylonitrile content that ranges from approximately 26% by weight to approximately 35% by weight and polybenzoxazole (“PBO”) fibers. The NBR may be a copolymer of acrylonitrile and butadiene and may be present in the insulation composition in a range of from approximately 45% by weight to approximately 56% by weight of a total weight of the insulation composition. The PBO fibers may be present in a range of from approximately 3% by weight to approximately 10% by weight of a total weight of the insulation composition. A rocket motor including the insulation composition and a method of insulating a rocket motor are also disclosed.Type: GrantFiled: August 18, 2005Date of Patent: April 15, 2008Assignee: Alliant Techsystems Inc.Inventors: Himansu M. Gajiwala, David G. Guillot
