  • Ethylene vinyl acetate compositions for dielectric sealing applications
    Patent number: 4746579
    Abstract: A binder suitable for dielectric sealing may be prepared comprising a blend of a polyvinyl halide emulsion and an aqueous emulsion comprising a vinyl ester of an alkanoic acid interpolymerized with(a) 5 to 28% by weight of ethylene;(b) 0.5 to 4% by a weight of an N-methylol containing copolymerizable monomer;(c) 0 to 3% by weight of a latex stabilizer; and(d) 0 to 1% by weight of at least one polyunsaturated copolymerizable monomer,the binder having a Tg of -15.degree. to +35.degree. C. and being buffered to a pH greater than 7.
    Type: Grant
    Filed: May 7, 1987
    Date of Patent: May 24, 1988
    Assignee: National Starch and Chemical Corporation
    Inventors: Marie E. Yannich, Howard G. Katz

  • Ethylene vinyl acetate compositions for paper saturation
    Patent number: 4659595
    Abstract: Saturated paper products characterized by an excellent balance of toughness, strength, fold, tear and delamination resistance comprising a sheet of loosely bonded cellulose fibers saturated with an aqueous emulsion prepared by the emulsion polymerization of:(a) a vinyl ester of an alkanoic acid interpolymerized with:(b) 5 to 30% by weight of ethylene;(c) 0.5 to 6% by weight of an N-methylol containing copolymerizable monomer;(d) 1 to 5% by weight of an olefinically unsaturated carboxylic acid;(e) 0.2 to 3% by weight of a latex stabilizer; and(f) 0 to 1% by weight of at least one polyunsaturated copolymerizable monomer.
