  • Barrier film structures
    Patent number: 4847155
    Abstract: Articles useful as RF-sealable packaging materials comprise a halopolymer barrier layer coated onto, or adhered to, a carbon monoxide-containing polymer, wherein the carbon monoxide-containing polymer provides RF-sealability to the structure. Other layers of materials may be employed as part of the packaging material.
    Type: Grant
    Filed: September 30, 1987
    Date of Patent: July 11, 1989
    Assignee: The Dow Chemical Company
    Inventors: Gerald M. Lancaster, David C. Kelley, Russell H. Cramm, Charles V. Neywick

  • Acrylate compositions
    Patent number: 3993716
    Abstract: The formation of non-aqueous polymeric dispersions, solutions, hydrosols and collodial suspensions by polymerizing vinyl monomers (A) in a hydrocarbon medium containing dissolved therein a stabilizing component (B) comprising an acrylic polymer previously formed from acrylic monomers (E). The invention comprises use, in (B), of minor proportions of (2-(1-aziridinyl)-ethyl- methacrylate to provide, by reason of its high reactivity, higher molecular weight backbones (B) and simultaneously by reason of its high functionality, to provide active sites for grafting side chains onto backbone (B). Furthermore, the reactivity thereof can make the final product self-cross-linking. The above system produces a dispersion of a vinyl polymer (C) formed from the polymerized vinyl monomers (A) in the hydrocarbon medium wherein a modified stabilizer (D) is formed either in situ from a precursor or in a preliminary separate step by grafting a portion of the vinyl monomers (A) onto the soluble polymeric stabilizer backbone (B).
