Patent number: 8268926Abstract: Particle-toughened polymer compositions include a base polymer formulation and a plurality of toughening particles. In certain embodiments, the base polymer formulation includes bismaleimides or other polymer resins capable of high temperature service. A first plurality of toughening particles may include core shell rubbers. A second plurality of toughening particles may be selected from a variety of polymer compositions, including polyimides, polyether ketone (PEK), polyether ether ketone (PEEK), polyether ketone ketone (PEKK), polyether imide, polyether sulfones, and polyphenylene oxide. It is found that increasing concentration of the core shell rubbers may improve the toughness of the composition while preserving thermal properties of the composition, such as glass transition temperature.Type: GrantFiled: May 25, 2010Date of Patent: September 18, 2012Assignee: Cytec Technology Corp.Inventors: Mark Richard Bonneau, Jack Douglas Boyd, Gordon T. Emmerson, Scott D. Lucas, Stephen J. Howard, Spencer Donald Jacobs

Publication number: 20120214908Abstract: A composition suitable for forming a paint marking on a roadway comprises a polyfunctional acrylate having at least four acrylate groups, an epoxy component and a polyfunctional amine. The polyfunctional acrylate reacts with the polyfunctional amine to form an adduct with secondary amine groups. The secondary amine reacts with the epoxy component to yield a chemically high crosslinked material having a no track time of less than about five minutes.Type: ApplicationFiled: February 19, 2011Publication date: August 23, 2012Inventor: Ling Tan
