Process for the preparation of an aqueous emulsion of a midblock sulfonated block copolymer
The present invention concerns aqueous emulsions and a process for preparing aqueous emulsions of a midblock sulfonated styrenic block copolymer comprising at least two non-sulfonated polymer end-blocks A and at least one sulfonated block B, comprising the steps of providing a cement of a midblock sulfonated styrenic block copolymer in the apolar solvent, mixing the cement with a co-solvent to form a mixture, emulsifying the mixture in the absence of a surfactant with water to produce an emulsion, and removing the hydrocarbon solvent and any optional co-solvent from the emulsion to produce the aqueous emulsion. The resulting emulsion of the midblock sulfonated styrenic block copolymer has relatively small particle diameters.

STYRENIC BLOCK COPOLYMERS AS THERMALLY-ACTIVATED VISCOSIFIERS FOR OILFIELD APPLICATIONS
Provided herein is a dispersion composition comprising a blend of a semi-crystalline, selectively hydrogenated block copolymer and a low polarity fluid for oilfield applications. The block copolymer comprises blocks of semi-crystalline hydrogenated polybutadiene, blocks of poly(mono alkenyl arenes), and blocks of hydrogenated, non-crystalline conjugated dienes. The dispersions can be converted to thixotropic fluids or cohesive gels and find application as insulating packer fluids, fluid loss pills, drilling fluids and completion fluids.

C08L 53/02 - Compositions of block copolymers containing at least one sequence of a polymer obtained by reactions only involving carbon-to-carbon unsaturated bondsCompositions of derivatives of such polymers of vinyl aromatic monomers and conjugated dienes
A composition is disclosed, comprising a block copolymer, at least one homopolymer or copolymer of butene, and at least one olefin homopolymer or copolymer, wherein said block copolymer has hydrogenated low-vinyl polybutadiene end blocks with a specific gravity>0.85 g/cc, and a controlled distribution midblock of polyalkenyl arene/hydrogenated diene. Although the block copolymer has a preferred linear structure as a triblock copolymer, it may also be branched or radial coupled copolymer that has at least 2 arms or more. The composition is useful for rotational molding, slush molding, injection molding, extrusion or compression molding, or thermoforming or calendering for making articles that are resistant to chemicals such as diesel fuel, for the automotive market, for example. The MFR of the block copolymer is 1 to about 50 g/10 min. at 230° C., with a wt. of 2.16 kg.
