The method includes treating high aspect ration clay nanoparticles to make them organophilic. The treated nanoparticles are then mixed in a polymer resin in such a way as to form an intercalated mixture. A curing agent is added to the mixture, and the mixture is allowed to set. When set the resulting intercalated mixture produces an acoustically clear, low permeability polymer coating.Type: GrantFiled: April 13, 2010Date of Patent: June 25, 2013Assignee: The United States of America as represented by the Secretary of the NavyInventor: Thomas S.

Publication number: 20130131222Abstract: The present invention relates to polyurethane polymers comprising as part of its polymer backbone biobased ?-hydroxyfatty acids or derivatives thereof, processes for the preparation thereof, and compositions thereof having improved properties. The polyurethanes of the present invention are prepared from copolyester prepolymers comprising the biobased ?-hydroxyfatty acids that may also contain additional components that can be selected from aliphatic or aromatic diacids, diols and hydroxyacids obtained from synthetic and natural sources. The biobased ?-hydroxyfatty acids that comprise the polyurethanes and copolyester prepolymers of the present invention are made using a fermentation process from pure fatty acids, fatty acid mixtures, pure fatty acid ester, mixtures of fatty acid esters, and triglycerides from various sources.Type: ApplicationFiled: March 11, 2011Publication date: May 23, 2013Applicant: SyntheZyme LLCInventor: Richard A.

Publication number: 20130074718Abstract: A laser-engraveable flexographic printing precursor or patternable element comprises a laser-engraveable layer having two orthogonal dimensions. This laser-engraveable layer comprises one or more elastomeric resins and non-metallic fibers that are oriented in the laser-engraveable layer predominantly in one of its two orthogonal dimensions. The non-metallic fibers have an average length of at least 0.1 mm and an average diameter of at least 1 ?m. The oriented non-metallic fibers reduce curl and shrinkage in the precursor and improve print quality and press life.Type: ApplicationFiled: September 27, 2011Publication date: March 28, 2013Inventors: Ido Gal, Ophira Melamed

Patent number: 8404084Abstract: A filler treatment process enhances the fixation of anionic latex on filler in a short time. Anionic polymer dispersions (latex) are added to papermaking filler slurries at ambient temperature and then mixed with water of temperature higher than the glass transition temperature (Tg) of the latex used. The anionic latexes applied by this process are totally and irreversibly fixed or bound onto the filler particles and the treated filler particle agglomerate to form an aggregated filler slurry which is stable over time. The latex-treated filler slurry can be added to papermaking furnishes at any point prior to the headbox of the paper machine or stored for later use. The latex-treated filler slurry improves filler retention, only slightly reduces sheet strength and improves sizing performance.Type: GrantFiled: August 30, 2011Date of Patent: March 26, 2013Assignee: FPInnovationsInventors: Makhlouf Laleg, Roderick Collins, Danielle Gagne, Steven Middleton

Patent number: 8399551Abstract: An embodiment of the present invention is a nanocomposite comprising a clay and an elastomer comprising at least C2 to C10 olefin derived units; wherein the elastomer also comprises functionalized monomer units pendant to the elastomer. Desirable embodiments of the elastomer include poly(isobutylene-co-p-alkylstyrene) elastomers and poly(isobutylene-co-isoprene) elastomers, which are functionalized by reacting free radical generating agents and unsaturated carboxylic acids, unsaturated esters, unsaturated imides, and the like, with the elastomer. The clay is exfoliated in one embodiment by the addition of exfoliating agents such as alkyl amines and silanes to the clay. The composition can include secondary rubbers such as general purpose rubbers, and curatives, fillers, and the like. The nanocomposites of the invention have improved air barrier properties such as are useful for tire innerliners and innertubes.Type: GrantFiled: May 30, 2003Date of Patent: March 19, 2013Assignee: ExxonMobil Chemical Patents Inc.Inventors: Caiguo Gong, Anthony Jay Dias, Andy Haishung Tsou, Beverly Jean Poole, Kriss Randall Karp
