    摘要： There is a viscoelastic fluid. The fluid has one or more cationic surfactants selected from the group consisting of certain quaternary salts, certain amines, and combinations thereof; one or more anionic polymers/anionic surfactants; one or more of certain zwitterionic/amphoteric surfactants; and water. There is also a method of fracturing a subterranean formation. The viscoelastic fluid is pumped through a wellbore and into a subterranean formation at a pressure sufficient to fracture the formation.

    摘要： The present invention relates to a photoinitiator composition that can be used to initiate polymerization upon exposure to radiation. The said composition includes both a composition which yields cations upon exposure to actinic radiation, such as an iodonium borate initiator and a stabilizing amino agent. The amino agent is a secondary or tertiary amine having general formula (VIII), a sterically arranged cyclic amine having general formula (IX), or an amine consisting of groups that have general formulas (VIII) and (IX) and that are interconnected. The compositions are particularly useful when used in conjunction with polyorganosiloxane monomers and when exposed to ultraviolet radiation.

    摘要： Disclosed is a process for making alkoxylates of organic compounds. The process requires a) providing an active hydrogen organic compound having 1 to 22 carbon atoms and b) alkoxylating the organic compound with an alkylene oxide in the presence of o catalytically effective amount of a catalyst compound corresponding to either formula (I) or formula (II): B(o)3 (I) H B(o)4 (II) wherein B is a boron atom and H is a hydrogen atom; o is a phenyl moiety having substituents selected from the group consisting of 1 to 5 fluorine atoms, 1 to 5 CF3 moieties, 1 to 5 OCF3 OR SCF3 moieties or OR; wherein C is a carbon atom, O is an oxygen atom, S is a sulfur atom and F is a fluorine atom; wherein R is a hydrogen atom or an alkyl or aryl group having from 1 to 22 carbon atoms. The process affords a product of very narrow molecular weight distribution with a low degree of both residual active hydrogen organic starting material and undesirable by-products.
