    摘要： Thermoplastic Vulcanizate (TPV) blends are disclosed wherein the otherwise generally compatible blend of thermo-plastic and crosslinked elastomer is made unexpectedly more compatible on the nano-scale, as evaluated Atomic Force Microscopy (AFM). The blends comprise a polyolefin matrix, domains of well-dispersed crosslinked olefinic rubber particles and the presence between the rubber particles of ligaments of a compatibilizing copolymer comprising olefin monomeric units and aromatic monomeric units. The addition of the compatibilizer increased the dispersion of olefinic rubber particles.

    摘要： A thermoplastic elastomer composition is disclosed, comprising at least one thermoplastic elastomer, a minor amount of at least one high molecular weight polydialkylsiloxane, and a minor amount of at least one fluoropolymer. Compositions of the invention have improved durability by virtue of their improved resistance to scratching and marring. Further, compositions of the invention are beneficially low friction as evidenced by a reduced coefficient of friction as compared to unmodified thermoplastic elastomers.

    摘要： A catalyst system is disclosed for use with elastomeric compositions, such as thermoset elastomers or thermoplastic elastomers. The catalyst system comprises at least one phenolic resin and at least one other ingredient selected from the group consisting of a non-transition metal halide and a nanoclay, provided that when the ingredient is nanoclay, the phenolic resin is brominated. Optionally, the catalyst system can include at least one acid or at least one hydrogen halide scavenger, or both. The catalyst system avoids the use of tin-containing materials, reducing environmental concerns. Elastomers and their preparation in the presence of the catalyst system are also disclosed, including the preparation of white elastomers.
