摘要： Oriented films are prepared. A thermoplastic vulcanizate, prepared by mixing at least 20 wt % of a thermoset rubber by weight of the total composition into a thermoplastic polymer are disclosed. After the mixture is prepared the thermoset rubber is entrained as discrete particles within the continuous thermoplastic polymer phase. The resulting composite is subjected to a stress either by pulling, blow molding, or any other film-forming process as is known in the art. This stress causes the continuous phase polymer molecules to become aligned or oriented in the direction in which the stress was applied, thus creating the oriented thermoplastic vulcanizate of the invention. This material has improved gas permeability and improved flexibility properties.

摘要： 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; the 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.
