Abstract: Disclosed are an associated copolymer, a method for preparation of a polymer and a polymer prepared with the method, a use of the associated copolymer and/or the polymer in drilling fluids, and a drilling fluid containing the associated copolymer and/or the polymer. The associated copolymer comprises acrylamide structural units, zwitter-ionic structural units, and cationic polyamine structural units at a specific proportion, and the cationic polyamine structural units have specific kinematic viscosity and cationic degree; thus, when the associated copolymer is used as a viscosity improver for drilling fluids, the obtained drilling fluid not only has favorable apparent viscosity after it is aged at a high temperature, but also has high dynamic shear force, and is resistant to high temperature up to 200° C. or above, resistant to NaCl up to saturated concentration, and resistant to CaCl2 up to 20 wt % concentration.

Abstract: Hydrogen storage fuel compositions comprising a mixture of at least one chemical hydride compound and at least one compound, polymer, carboxylic acid or salt that acts as a water surrogate source, and methods for thermally initiated hydrogen generation from fuel compositions, are disclosed. The water surrogate source/chemical hydride compositions are preferably solids, and may be powders, caplets, tablets, pellets or granules, for example. The water surrogate source/chemical hydride compositions may comprise alternating layers of the chemical hydride and of the water surrogate source.

Abstract: A branched composition can be formed by reacting a reagent containing a saturated hydrocarbon moiety in the presence of (a) a catalyst capable of activating a carbon-hydrogen bond therein and (b) a branching reagent having a moiety that binds to the carbon atom in the carbon-hydrogen bond upon extraction of the hydrogen atom from that carbon-hydrogen bond. Suitable catalysts are those that comprise a transition metal cation possessing multiple oxidation states that is embedded in an anion that is a transition metal oxide possessing a higher oxidation state for the metal therein than the metal in the cation.
