Patent number: 8153713Abstract: A core-shell particle is formed by a method that includes forming a crosslinked polyorganosiloxane core, reacting a graftlinking agent with the crosslinked polyorganosiloxane core, and polymerizing a poly(alkenyl aromatic) shell around the graftlinking agent-functionalized polyorganosiloxane core. The method produces a core-shell particle with improved adhesion between shell and core. The core-shell particle is useful as an impact modifier in thermoplastic compositions.Type: GrantFiled: November 7, 2008Date of Patent: April 10, 2012Assignee: Sabic Innovative Plastics IP B.V.Inventors: Amol Adhikrao Mohite, Jaykisor Pal, Sathya Narayanan, Satishkumar H.

Patent number: 8133964Abstract: The coating described herein attempts to provide this solution by synthesizing alkoxysilane-terminated N-substituted urea resins, then formulating them into moisture-curable single-component (1K) topside coatings. These coatings will provide greater external stability (to UV and visible radiation), cleanability, flexibility, cure times and lower VOC content than the currently qualified silicone alkyd topside coatings that are found on Navy ships. The single-component coating can include at least an alkoxysilane-terminated N-substituted urea resin, a reactive diluent, a pigment, a filler, and a catalyst. The resin can include an amino-functional silane substituted at the N-position and a non-aromatic isocyanate.Type: GrantFiled: June 29, 2010Date of Patent: March 13, 2012Assignee: Science Applications International CorporationInventor: Erick B.
