  • Publication number: 20180179372
    Abstract: A dynamically vulcanized alloy contains at least one isobutylene-based elastomer, at least one thermoplastic resin, a cure system, and a lubricant system. The lubricant system is comprised of a metal organic salt and a fatty acid having a phr ratio range of metal organic salt to fatty acid of 0.75:1 to 10:1. In the alloy, the elastomer is present as a dispersed phase of small vulcanized or partially vulcanized particles in a continuous phase of the thermoplastic resin. The alloy may be formed into blown films or extruded cast sheets and is useful in various applications, including tire innerliners and hose layers, where impermeability characteristics are desired for either the particular layer or the final article.

  • Patent number: 9546251
    Abstract: This invention relates to the preparation of a dynamically vulcanized alloy comprising at least one elastomer and at least one thermoplastic resin, having a G? at 1% strain and 100° C. as determined according to ASTM D7605 of about 4,500 to about 7,500 kPa. More specifically, the process produces dynamically vulcanized alloys with unique morphological features which have good impermeability and low temperature flexibility. In the process, the thermoplastic resin is added into the extruder in two stages with an intermediate addition of a compatibilizer. Also during the final addition of thermoplastic resin, the elastomeric curatives are added to the extruder.

  • Patent number: 8962762
    Abstract: Provided are thermoplastic polymer compositions having a single melting point, articles made therefrom, and methods for elevating the melting point of low melting point polymers. Thermoplastic polymer compositions are composed of one or more high melting point polyolefins and a thermoplastic component that includes a low melting point polypropylene. High melting point polyolefins are composed of a stereoregular polypropylene having a tacticity similar to the low melting point polypropylene. The low melting point polypropylene includes, for example, propylene homopolymers and copolymers composed of propylene and one or more comonomers. Thermoplastic polymer compositions may also optionally contain any of the various additives commonly used in such polymer compositions, such as for example oils, etc. In one embodiment, thermoplastic polymer compositions are thermoplastic elastomer compositions that include an elastomeric component composed of an elastomer or rubber.
