  • Coalescing aid for high nitrile copolymer latex coatings
    Patent number: 4379875
    Abstract: Nitrile barrier resin latexes containing a coalescing agent which (1) is a solvent for the nitrile barrier resin, (2) has a boiling point between 100.degree. and 300.degree. C., and (3) does not azeotrope with water are excellent oxygen barriers and have good chemical resistance when coated on various substrates. Especially effective coalescing agents are selected from the group consisting of dimethyl formamide, dimethyl acetimide, methyl pyrrolidone, dimethyl sulfoxide, glycol carbonate and tetramethylene sulfone.

  • Tie layer for co-extruded acrylonitrile copolymers
    Patent number: 4359506
    Abstract: A synthetic resin laminated structure is produced by bonding together in a molten state a layer of a (I) nitrile barrier resin, (II) a layer of a polymer mixture comprising a nitrile barrier resin and a halogenated polyolefin, and (III) a layer of a thermoplastic resin. The thermoplastic resins useful in this invention include polyolefins such as polyethylene and polypropylene, polyvinylchlorides, styrene containing polymers such as ABS, SAN and polystyrene, polycarbonates, polyurethanes, polysulfones, polyamides and nitrile barrier resins.

  • Blends of high nitrile resins and hydrophobic nylons
    Patent number: 4307207
    Abstract: Impact resistant polymeric compositions are composed of a blend of a high nitrile resin and a hydrophobic nylon. The high nitrile resins useful in this invention are those produced by polymerizing a major proportion of a monounsaturated nitrile, e.g. acrylonitrile, and a minor proportion of another monovinyl monomer component, e.g. methyl acrylate, copolymerizable therewith optionally in the presence of a preformed rubber. The hydrophobic nylons useful in this invention comprise nylon-11, nylon-12 anc cyclic nylons.

  • Adhesion promoter for acrylonitrile copolymer latex coatings
    Patent number: 4243707
    Abstract: In the coating of the surface of metal substrates with an acrylonitrile copolymer from an aqueous latex of said copolymer, the adhesion of the copolymer to the metal surface is improved by the inclusion in the latex of a condensation product of certain metal hydroxides or borates with a certain type of phosphate emulsifier.
