摘要： This invention relates to an improved process for the formation of an improved gel-free neutralized sulfonated elastomeric polymer having about 10 to about 50 meq. unneutralized sulfonate groups, wherein the unneutralized sulfonate groups are neutralized with a metal counterion being selected from the group including lithium, sodium, potassium, cesium, barium, calcium, magnesium, zinc, lead, iron (II), copper (II), mercury (II), and nickel. A cement of an elastomeric polymer having olefinic functional groups dissolved in a non-reactive solvent is contacted with a sulfonating agent such as an acyl sulfate thereby sulfonating the elastomeric polymer, and the sulfonation reaction is subsequently quenched by the addition of isopropanol at a concentration level of about 5 to about 30 volume percent based on a volume of the non-reactive solvent. The unneutralized sulfonated elastomeric polymer is then neutralized with a neutralizing agent dissolved in water, the water being at a concentration level of less than about 2.5 volume percent based on the volume of the non-reactive solvent thereby forming a gel-free cement of the neutralized sulfonated elastomeric polymer having a Brookfield viscosity at room temperature of less than about 20,000 cps.

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.
