Patent number: 6403216Abstract: A synthetic fiber which is excellent in moisture-absorbing/releasing property and exhibits high elongation and high stretch recovery, characterized in that it has moisture absorption ratios of 0.5 to 4.0% by weight in environments of 20° C.×65% RH and that of 4.5% by weight or more in environments of 30° C.×90% RH, respectively, and also has a difference between the absorption ratios in both the environments of 4.0% by weight or more. The representative examples of such fibers include polyurethane synthetic fiber and polyether synthetic fiber. The synthetic fiber maintains a high strength at break of an elastic fiber component thereof also in the state of having absorbed moisture, is excellent in color fastness to rubbing, and can be used for manufacturing a stretch fiber fabric product excellent in comfort through blending with another fiber material.Type: GrantFiled: August 9, 2001Date of Patent: June 11, 2002Assignee: Asahi Kasei Kabushiki KaishaInventors: Masanori Doi, Takeshi Sugaya, Sueo Ohashi

Patent number: 6399698Abstract: An isocyanate prepolymer for application in polyurethanes. The prepolymer is synthesized by combining epoxidized natural oils with isocyanates and a catalyst. The prepolymer contains oxazolidone rings that will react with polyols to form polyurethane. The invention provides a method of using a renewable resource in a fast, simple process to produce substantial amounts of isocyanate prepolymer and a minimum of homopolymers.Type: GrantFiled: October 26, 2000Date of Patent: June 4, 2002Assignee: Pittsburg State UniversityInventors: Zoran S. Petrovic, Ivan J. Javni

Patent number: 6395861Abstract: A fast-curing polyurethane coating system for a game ball is described herein. The coating system comprises a mixture of a polyol, an isocyanate, a solvent and a surprisingly high level of catalyst which accelerates the curing process. The coating is a two-part polyurethane system which is preferably applied by spraying. The coating is particularly well-suited for use on golf balls, and also can be applied to other game balls such as softballs, baseballs, and cricket balls.Type: GrantFiled: March 1, 1996Date of Patent: May 28, 2002Assignee: Spalding Sports Worldside, Inc.Inventor: Thomas J. Kennedy, III

Patent number: 6369183Abstract: A composition of matter, comprising: a chemically functionalized carboxylate-alumoxane that is functionalized with a chemically reactive substituent, and a reactive compound, wherein the chemically reactive substituent reacts with the reactive compound so as to link the carboxylate-alumoxane to the reactive compound and form a polymer matrix. The functional groups on the carboxylate-alumoxane can vary depending on the desired properties of the matrix. Also, the composition of matter may comprise a cross-linked matrix in which the cross-linked components consist of functionalized alumoxanes.Type: GrantFiled: August 13, 1998Date of Patent: April 9, 2002Assignee: Wm. Marsh Rice UniversityInventors: Ronald Lee Cook, Andrew Ross Barron, Kevin Joseph Gleason, David Brent MacQueen, Georgette Laila Siparsky, Yoshihiro Koide, Cullen Taylor Vogelson
