    摘要: 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.

    摘要: The thermoplastic elastomer compositions contain a continuous phase or matrix of an engineering thermoplastic such as ester polymer and a discontinuous phase of an acrylic rubber which is cured substantially by using epoxidized oils. The cured composition which can be dynamically vulcanized has good physical properties such as tensile strength, elongation, and high temperature resistance.

    摘要: Disclosed herein are low Shore A Hardness thermoplastic vulcanizate compositions having high Rebound values. In at least one exemplary embodiment, the compositions include a dispersed at least partially vulcanized rubber component; a thermoplastic component; and process oil; wherein the weight ratio of the thermoplastic component to the rubber component ranges from 80:20 to 15:85; and the thermoplastic component comprises more than 80 wt % of a polypropylene (preferably a random propylene copolymer) having a melting point less than about 105° C. The compositions can be used in molded products, consumer goods and the like.
