摘要
This invention involves a process for the utilization of an unusual memory characteristic which is present in neutralized sulfonated elastomeric materials, wherein the process includes the steps of distorting or compressing the neutralized sulfonated elastomeric article, then heating the article to a selected elevated temperature, holding the article at the elevated temperature for a limited time while maintaining the distorted shape, cooling the article to near room temperature, and releasing it from the device used to compress or distort it. The released cooled elastomer does not return to its original form, but rather substantially retains the distorted shape for an indefinite period of time. The elastomer in the distorted shape is heated to an appropriate elevated temperature thereby allowing the article to recover towards its original undistorted shape.
