Abstract: Disclosed is a composition and use thereof for the recovery of hydrocarbon fluids from a subterranean reservoir. More particularly, this invention concerns sulfonated epoxy resin polymers comprising an epoxide-containing compound, a primary amino sulfonate, and optionally one or more of a primary monoamine alkylene oxide oligomer, that modify the permeability of subterranean formations and increase the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.

Abstract: Disclosed herein is a wind turbine rotor which includes a plurality of blades and a hub root, wherein at least one blade is provided with at least one electrostatic noise grounding system. The electrostatic noise grounding system includes an insulated rod having a first end and a second end, a conductive core passing through the insulated rod, a first conductive element connected to the conductive core at the first end of the insulated rod, and a second conductive element competed to the conductive core at the second end of the insulated rod. The electrostatic noise grounding system is secured to a portion of the rotor (e.g., blade bearing housing or blade bearing housing bolted connection) such that the first conductive element is in direct physical contact with at least a portion of the surface of at least one blade and the second conductive element is in direct physical contact with at least a portion of the surface of the hub root.

Abstract: A compound (monomer) comprising i) one or more dienophile groups (A-functional groups), ii) one or more ring structures comprising two conjugated carbon-to-carbon double bonds and a leaving group L (B-functional groups), and iii) one or more chemically bound mesogenic poragen forming moieties, characterized in that the A-functional group is capable of reaction under cycloaddition reaction conditions with the B-functional group to thereby form a cross-linked, polyphenylene polymer.

Abstract: A compound useful in the formation of polymeric dielectric films for semiconductor devices and the resulting cured films and devices, said compound comprising i) three or more dienophile groups (A-functional groups) and ii) a single ring structure comprising two conjugated carbon-to-carbon double bonds and a leaving group L (collectively referred to as a B-functional group), characterized in that one A-functional group of one molecule of the compound is capable of reaction under cycloaddition reaction conditions with the B-functional group of a second molecule and elimination of the leaving group L, to thereby form a polymer.

Abstract: A monomer suitable for use in forming low dielectric constant films in semiconductor devices comprising i) two dienophile groups (A-functional groups) attached to a single aromatic ring and ii) a second ring structure comprising two conjugated carbon-to-carbon double bonds and a leaving group L (B-functional group), characterized in that said single aromatic ring is directly covalently attached to one of the double bonded carbons of the B functional group or to a fused aromatic ring containing two such double bonded carbons of the B-functional group, and one A-functional group of one monomer is capable of reaction under cycloaddition reaction conditions with the B-functional group of a second monomer to thereby form a polymer.
