  • Publication number: 20040204551
    Abstract: An epoxy/elastomer adduct, a method of forming the adduct and materials and articles incorporating the adduct are disclosed. The adduct preferably includes up to about 60% by weight of an elastomeric component, up to about 90% by weight of an epoxy component and optionally one or more additives.

  • Publication number: 20040183702
    Abstract: An admixture of thermoplastic polymer (such as thermoplastic elastomer), cured elastomeric polymeric material (such as thermoset elastomer), and magnetizable (ferrite) powder provide a thermoplastic elastomer featuring a relatively high loading of a magnetizable material. The admixed magnetizable thermoplastic elastomer composition, optionally cured, provides robust material properties along with good forming properties for molding magnetic components. This material is advantageous for a magnetic target wheel in an encoder.

  • Patent number: 6624251
    Abstract: Disclosed are new fluid resistant, in particular resistant to chemically basic compounds, for example those compounds containing amines, and exceptional processing fluorine containing thermoplastic vulcanizate compositions comprising a continuous phase of at least one melt-formable thermoplastic fluorocarbon resin and a disperse phase consisting of a blend of at least two vulcanizable fluorine containing elastomers with at least one of the fluoroelastomers being a terpolymer of vinylidene fluoride/tetrafluoroethylene/propylene. The vinylidene fluoride/tetrafluoroethylene/propylene fluoroelastomer comprises between 5 and 95 weight percent of the total dispersed elastomer phase, which the total disperse elastomer phase comprises from between 40 and 90 weight percent based on the total amount of the continuous phase and the disperse phase combined.

  • Publication number: 20020198320
    Abstract: A fluorine containing thermoplastic vulcanizate composition includes a continuous phase of at least one melt formable thermoplastic resin and a discrete phase of a vulcanized perfluoroether elastomer. The perfluoroether elastomer comprises between 10 and 80 weight percent based on the total amount of the continuous phase and the disperse phase combined.

  • Patent number: 6147158
    Abstract: Blends of polyketone polymers with polyolefin polymers are described which are compatibilized by a reactive blend of a polyamide polymer and a maleated polyolefin polymer. The compatibilization is attained without chemical linkage between the compatibilizer and the polyketone polymer. Such compatibilized blends offer good mechanical properties and the ability to melt bond to both neat polyketone polymers and neat polyolefin polymers.

  • Patent number: 5936039
    Abstract: Processes for the preparation of a thermoplastic elastomer comprising a triblend of engineering resin, dynamically vulcanized alloy of thermoplastic olefin polymer and elastomeric copolymer, and a compatibilizer for the engineering resin and alloy. The compatibilizer can be formed in a separate step or in-situ in a one step process. The processes produce compositions which retain structural integrity at high temperature, and have good tensile properties, elongation and fluid resistance.
