摘要： Improvements in the treatment of wells that penetrate subterranean formations are accomplished through the use of a polymer solution which includes a neutralized ionomeric polymer dissolved in an organic solvent and a polar cosolvent. The polymer has a backbone that is substantially soluble in the organic solvent and pendant ionomeric groups that are substantially insoluble in the organic solvent. The polar cosolvent solubilizes the pendant ionomeric groups such that the polymer solution upon introduction into the well has a viscosity less than about 20,000 centipoises and upon mixing with water the polar cosolvent is taken up by the water causing the polymer to aggregate and increase in viscosity sufficient to form a plug. The polymer solution may be used in well drilling operations, well completion operations, and secondary recovery operations.

摘要： A process for fabricating a plastic, which plastic is either a thermoplastic ionomer or a multiphase graft or block copolymer of the ABA, ##STR1## or (AB).sub.n wherein n is greater than 1 and wherein the polymer blocks (A and B) are thermoplastic, incompatible with one another, and have different softening points, both softening points being substantially above room temperature when using the latter class of polymers. The material is first heated to a temperature above both softening points and formed into any desired shape, then cooled and re-formed into a new desired shape at a temperature between that of the softening points of the two blocks and finally cooled to a temperature below both softening points thereby retaining the shape last achieved. When using thermoplastic ionomers the process is similar. The material is heated above the softening point of the thermoplastic backbone and plasticizers are employed to disrupt the ionic domains. The process may be readily employed to prepare containers, bottles, or rigid foams and the like which may be shipped as compact materials and re-formed for actual use by simply reheating, etc.
