A thermoplastic elastomer is formed from a thermoplastic polymer such as a polyester, polycarbonate, or combinations thereof or a polyamide, which polymer is melt blended with an acrylic rubber. The acrylic rubber desirably has from about 0.5 to about 5 mole percent repeat units from halogen (desirably chlorine) containing monomer. Subsequently the acrylic rubber is crosslinked with 2,5-mercapto-1,3,4-thiadiazole or a derivative thereof. Such a thermoplastic elastomer may have a compression set less than 50% making it useful in applications involving continuous use under compression.
热塑性弹性体由热塑性聚合物(如聚酯、聚碳酸酯或其组合或聚酰胺)与丙烯酸橡胶熔融混合而成。丙烯酸橡胶最好具有约 0.5 至约 5 摩尔%的含卤素(最好是氯)单体重复单元。随后,丙烯酸橡胶与 2,5-巯基-1,3,4-噻二唑或其衍生物交联。这种热塑性弹性体的压缩永久变形小于 50%,可用于在压缩条件下连续使用。
