Abstract: The present invention discloses a class of water soluble complex polymers of relatively low molecular weight, which have been found to be improved drag reducing agents. These complex polymers are a mixture of a cationic copolymer having a water soluble polymer backbone and an anionic copolymer having a water soluble polymer backbone. The solutions of these complex polymers are improved drag reducing agents for aqueous systems at low concentrations (i.e., 10 to 500 ppm) relative to individual solutions of the copolymers which make upon the polymer complex.

Abstract: The invention provides a method for increasing the viscosity of halogenated (brominated) elastomeric copolymers of a C4 to C7 isomonoolefin (isobutylene) and a para-alkylstryrene (p-methylstyrene) by mixing the copolymer with a silica or clay particulate filler which has been contacted with an aminosilane containing at least one C1 to C4 alkoxy group and at least one primary, secondary or tertiary amine group. The resulting elastomer compositions are used to prepare thermoplastic elastomer blend compositions, containing more finely dispersed elastomers which results in compositions having improved mechanical properties.

Abstract: The present invention relates to a process for the viscosification of an aqueous liquid which includes the steps of forming a solvent system of an organic liquid or oil and a polar cosolvent, the polar cosolvent being less than about 15 weight percent of the solvent system, a viscosity of the solvent system being less than about 1,000 cps; forming an interpolymer complex of neutralized sulfonated polymer (water insoluble) and copolymer of styrene/vinylpyridine in the solvent system to form a solution, a concentration of the water insoluble interpolymer complex polymer in the solution being about 0.01 to about 0.5 weight percent, a viscosity of the solution being less than about 200 cps; and admixing or contacting said solution with about 5 to about 500 volume percent water, the water being immiscible with the organic liquid and the polar cosolvent and interpolymer complex transferring from the organic liquid to the water phase, thereby causing the water phase to gel (i.e., thicken). The large increase in viscosity of the aqueous phase is directly attributed to the formation of a large number of minute water-filled particles dispersed in the continuous aqueous phase.
