    摘要: This invention relates to a process for first preparing a free flowing finely divided powder of a neutralized sulfonated elastomer and subsequently and optionally admixing said formed powder with other agents such as fillers and oils thereby providing free flowing powders capable of being subsequently fabricated into tough elastomeric objects. The neutralized sulfonated elastomeric polymer can be converted into a free flowing finely divided powder which does not agglomerate or cold flow under ambient conditions by a variety of processes, preferably by a grinding process conducted at low temperatures. The formed powder of the neutralized sulfonated elastomeric polymer is blended with at least one chemical additive into a homogeneous mixture, wherein the chemical additive is selected from the group including fillers, polyolefinic thermoplastics, non-polar backbone process oils, lubricants or a metallic oxide and mixtures thereof. The homogeneous mixture is formed into a finished elastomeric article by conventional fabrication.

    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.
