    Abstract: A method of forming a cured coating composition on an automobile component is provided. The method utilizes a coating compound including a radical polymerizable compound and an organoborane initiator and includes the step of applying the coating composition to the automobile component. The organoborane initiator is complexed with a bi-functional noncyclic blocking agent that has a carbon backbone and two organoborane complexing moieties. The two moieties are different from each other and are selected from the group of an amine moiety, a thiol moiety, and a phosphine moiety. In addition, the two moieties are separated from each other by two to four carbon atoms to increase the nucleophilicity of the blocking agent towards the organoborane initiator. The organoborane initiator is decomplexed from the blocking agent thereby forming a radical that is used to polymerize the radical polymerizable compound and cure the coating composition on the automobile component.

  • Patent number: 8617657
    Abstract: A method of making a block polyimide copolymer containing a first small block copolymer segment and a second larger block segment includes the steps of (a) reacting a first aromatic acid dianhydride with an aromatic diamine in a molar ratio from about 10:100 to about 50:100, respectively, to obtain the small block copolymer, (b) reacting the small block copolymer and excess amount of diamine with a second acid dianhydride in such a quantity that a total aromatic acid dianhydride and a total aromatic diamine are equimolar to obtain a precursor solution containing the first small block copolymer segment and the second larger block segment, (c) forming a film, laminate, or coating on a substrate, and (d) cyclodehydrating the film, laminate, or coating by chemical or thermal imidization.

  • Patent number: 8597737
    Abstract: The method of carbo-nitriding alumina surfaces is a process for applying a carbo-nitride coating to an alumina or alumina-based composite surface. The method involves the step of applying a phenolic resin to the alumina surface in a thin, uniform film. The resin-coated alumina surface is maintained in a controlled chamber at about 8 bar pressure at a temperature of about 175° C. for about 2 hours. The surface is then heated at about 400° C. for several hours in an argon atmosphere. This converts the phenolic resin to carbon. The carbon coated alumina surface is then scanned by a laser beam while applying nitrogen under pressure. The end result is the conversion of the alumina at the surface to aluminum carbo-nitride, the oxygen being released in the form of carbon dioxide.

  • Patent number: 8580348
    Abstract: The present invention provides a method for treating textile material to confer flame retardant properties, the method comprising the steps of impregnating the material with an aqueous solution of a treatment agent which is a poly(hydroxyorgano)phosphonium compound; drying the impregnated material; curing the dried impregnated material with ammonia to produce a cured, water-insoluble polymer which is mechanically fixed within the fibers of the material; oxidizing the cured polymer to convert trivalent phosphorus to pentavalent phosphorus; and washing and drying the material; wherein one or both of steps (d) and (e) result in the co-production of an aqueous effluent; and wherein the conditions are controlled such that the atomic ratio of N:P present on the material increases during step (c) by 0.8 or more.

  • Publication number: 20130293884
    Abstract: The present invention is directed to self-assembled nanoparticle arrays, methods of making the nanoparticle arrays, and methods of using the nanoparticle arrays in spectroscopic methods for detecting targets of interest. The present invention is also directed to a fabrication method for surface-enhanced Raman scattering (SERS) substrates that possess a unique combination of three highly desirable attributes: (a) the SERS substrates can be tuned to match the laser wavelength of operation and maximize the enhancement factor for the particular Raman instrument and analyte in use; (b) the SERS substrates have a highly reproducible enhancement factor over macroscopic sampling areas; and (c) the fabrication method is achieved without resorting to expensive, slow nano-lithography tools.
