Abstract: The present invention is related to hydrocarbon compositions comprising butanol that have substantially the same or improved performance properties than comparable hydrocarbon compositions comprising ethanol and to methods for identifying such compositions.

Abstract: Peroxide curable fluoroelastomer compositions and articles made therefrom are disclosed. The compositions contain 5 to 45 weight percent, based on total weight of all fluoroelastomers present in the composition, of a blend of dynamically cured fluoroelastomer particles in an uncured fluoroelastomer. The compositions are unfilled, but have tensile properties adequate for many end use applications and are particularly useful as seals in semiconductor manufacturing equipment.

Abstract: Copolymer comprising at least 50 mol percent up to 85 mol percent tetrafluoroethylene (TFE), from 10-35 mol percent 3,3,3-trifluoropropylene (TFP), and from 0.5-15 mol percent of a fluorinated ethylenically unsaturated monomer of the formula RCF?CR2 wherein R, which can be the same or different, is selected from the group consisting of H, F, Cl, Br, I, alkyl of from 1 to 8 carbon atoms, perfluoroalkyl of from 1 to 8 carbon atoms, and perfluoroalkylether of from 1 to 8 carbon atoms are useful as process aids and for fuel barrier applications in flexible hose constructions.

Abstract: Laminates of low swell elastomer, non-elastomeric fluoropolymer, and elastomer provide an excellent combination of flexibility and fuel permeation resistance.
