  • Patent number: 9056972
    Abstract: Barrier films made from a composition comprising vinylidene chloride (VDC) interpolymer and poly(butylene succinate) (PBS) exhibit improved tear resistance in both the machine and cross directions without a significant deterioration in oxygen transmission rate as compared to barrier films made under like conditions and from a composition alike in all respects except that the PBS is replaced with additional VDC interpolymer.

  • Publication number: 20140200283
    Abstract: A polymeric nanofoam has a continuous polymer phase containing at least one (meth)acrylic-free acrylonitrile-containing copolymer and at least one (meth)acrylic polymer where the concentration of (meth)acrylic polymer is in a range of 5-90 weight-percent of the total continuous polymer phase while the amount of methacrylic copolymer is 50 weight-percent or less of the total continuous polymer phase; the polymeric foam having a porosity of at least 50%, an absence of nano-sized nucleating additives and at least one of the following: (a) a number average cell size of 500 nanometers or less; and (b) an effective nucleation site density of at least 1×1014 sites per cubic centimeter of prefoamed material. The total weight of copolymerized acrylonitrile is in a range of 3-28 weight-percent based on total continuous polymer phase weight. At least one (meth)acrylic-free acrylonitrile-containing copolymer has a higher glass transition temperature than all of the (meth)acrylic polymers.

  • Patent number: 8592518
    Abstract: The present invention provides thermosetting aqueous binder compositions of one or more cyclic enamine, including bis-enamines and di- or higher functional enamines, optionally containing a water soluble or dispersible or dispersible primary amine compound. The binders are at least substantially formaldehyde free, need no polycarboxylic or polycarboxylate component, and yet provide excellent hot wet tensile strength when cured for as little time as a minute or less in use.

  • Patent number: 8298638
    Abstract: The invention includes a copolymer of vinylidene chloride with at least one monounsaturated comonomer and at least one branching monomer in an amount sufficient to increase molecular weight over that of a polymer prepared using the same process and same monomers in the same relative amounts except without the branching monomer, but preferably the branching monomer is present in a quantity not sufficient to result in measurable crosslinking as determined by solubility in tetrahydrofuran at up to 83° C. The invention includes a process for making the polymer and processes for forming the copolymer or compositions thereof as well as articles comprising the copolymer and compositions thereof. The copolymer exhibits improved bubble stability and is particularly useful for processes in which the copolymer is at least partially oriented in formation such as blow molding, formation of monofilament fiber and film blowing.
