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, ##EQU1## 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 plasticisers 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.

摘要： This invention relates to an improved process for the manufacture of a blend composition of a neutralized sulfonated elastomeric polymer which includes the steps of sulfonating an elastomeric polymer dissolved in a solvent to form an acid form of the sulfonated elastomeric polymer. The solution of the acid form of the sulfonated elastomeric polymer is quenched with an oxirane to form a polymeric hydroxyalkyl sulfonate. A non-polar backbone process oil is added thereby plasticizing the polymeric backbone of the hydroxyalkyl sulfonate. The hydroxyalkyl sulfonate is reacted with a metal carboxylate to form equal molar portions of a solid gel-free neutralized sulfonated elastomeric polymer and a hydroxyalkyl carboxylate ester.

摘要： Polymers having one or more sulfonic acid groups covalently bonded to one or more carbon atoms including the polymer are stabilized against thermal and hydrolytic degradation by reaction with an oxirane. The solid, gel-free hydroxyalkyl sulfonates thus formed are readily converted to thermoplastic ionomers by reaction with a metallic base or salt of a weak acid. The polymeric hydroxy alkylsulfonates possess a low melt viscosity and thus are readily mixed with neutralizing agents, plasticizers or other polymers and thereafter converted to ionomers by reaction with the neutralizing agent which is a metallic base or salt of a weak acid. The formulated solid gel-free ionomers are thermoelastic in nature and can be extruded, injected molded, and compression molded to useful products.
