    摘要: 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.

    摘要: 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.
