  • Patent number: 6153680
    Abstract: Thermoplastic polymer alloy compositions and a process for preparing the compositions are provided comprising a blend of polypropylene, uncrosslinked ethylene copolymer, ionomeric copolymer of ethylene and .alpha.,.beta.-unsaturated C.sub.3 -C.sub.8 carboxylic acid, crosslinking agent, and silicone elastomer. The compositions may further comprise particulate filler, color concentrate and/or coloring pigment. The compositions are particularly useful for forming interior skin sheets for applications where low gloss and high scuff resistance are desired without the need for painting. A one step process for preparing moldable sheets from the thermoplastic polymer alloy compositions by in-line compounding and reactive extrusion is also provided which eliminates separate compounding and pelletizing processing steps as precursors to the sheet extrusion process.

  • Patent number: 6054531
    Abstract: Weatherable thermoplastic compositions, such as a copolymer of styrene and acrylonitrile (SAN) are provided having improved impact strength. Improvements in thermoplastic composition properties are the result of the incorporation of the graft of an emulsion polymerized cross-linked poly(acrylate) rubber. The emulsion polymerized cross-linked poly(acrylate) rubber is synthesized in the presence of an effective amount of an alpha-alkylstyrenic monomer, such as alpha-methylstyrene dimer; the emulsion polymerized cross-linked poly(acrylate) rubber can be monomodal or bimodal.

    Abstract: A process for producing a conductive polyaniline is disclosed. The process includes mixing an aniline monomer, a water-immiscible organic solvent, at least one protonic acid doping agent and water together to form an emulsion via agitation, stopping agitation to allow the emulsion to separate into an aqueous phase and a non-aqueous phase, separating the non-aqueous phase from the aqueous phase, and adding an oxidation agent into the non-aqueous phase to carry out polymerization. A non-aqueous in-situ formed transparent polyaniline solution prepared by the process is also disclosed.

  • Patent number: 6031023
    Abstract: Novel white board dry erase ink compositions are provided which are comprised of poly(oxyalkylene) substituted colorants, volatile solvent vehicles, and binder resins. The binder resin is insoluble within the alcohol of the volatile vehicle; however, the degree of alkoxylation on the colorant aids in solubilizing the binder resin within the entire solution. Once the composition is transferred to a white board, the solvent evaporates, leaving the binder resin and colorant as a friable discontinuous film which is easily removed from the writing surface. The inventive composition has improved erasability, writability, stability within the marker stylus, and washability from skin and fabrics. Markers and methods of producing the ink composition are also provided.
