| 20080200573 | Flame Retarded Styrenic Foams and Foam Precursors - Styrenic polymer foams, especially expanded and/or extruded styrenic polymer foams, are flame retarded by use of one or more flame retardant additives. These additives are i) a diether of tetrabromobisphenol-S, which ether groups do not contain bromine and wherein at least one of the ether groups is an allyl group; ii) a diether of tetrabromobisphenol-S, wherein at least one of the ether groups contains bromine; iii) a substituted benzene having a total of 6 substituents on the ring and wherein at least 3 of the substituents are bromine atoms and at least two of the substituents are C1-4 alkyl groups; iv) tribromoneopentyl alcohol; v) a tris(dibromoalkyl) benzenetricarboxylate in which each dibromoalkyl group contains, independently, 3 to 8 carbon atoms; vi) a brominated polybutadiene which is partially hydrogenated and/or aryl-terminated; vii) at least one brominated allyl ether of a novolac; viii) a brominated poly(1,3-cycloalkadiene); ix) a brominated poly(4-vinylphenol allyl ether); x) a brominated N,TSP-phenylenebismaleimide; xi) a brominated N,N′-(4,4′-methylenediphenyl)bismaleimide; xii) a brominated N,N′-ethylenebis-maleimide; xiii) ethylenebis(dibromonorbornane-dicarboxrmide); xiv) tetrabromobisphenol-A; or xv) a combination of any two or more of i) through xiv). | 08-21-2008 |
| 20090247804 | METHODS FOR CONVERSION OF METHANE TO USEFUL HYDROCARBONS AND CATALYSTS FOR USE THEREIN - Methods are provided for converting methane to useful hydrocarbons. In the methods provided, a fluid comprising methane and hydrogen is combined with a catalyst composition derived from at least an aluminum compound, such as an aluminum halide, an aluminum alkyl, or a aluminum hydrate, and a second component such as a transition metal halide, a transition metal hydride, or a zero-valent metal, to produce heavier hydrocarbons. | 10-01-2009 |
