  • Patent number: 8008373
    Abstract: A biodegradable thermoplastic polymer masterbatch composition comprising a blend of at least one biodegradable thermoplastic polymer containing high loading of a particulate filler uniformly dispersed therein. The amount of the biodegradable thermoplastic polymer is generally from about 25% to about 50% by weight and the amount of the filler is from about 75% to about 50% by weight, based upon the total amount of one biodegradable polymer and the at least one filler. The uniform dispersion of the fillers is desirably obtained by adding small particles of the filler to a melt of the biodegradable polymer and blending using high shear equipment with special screw geometry. The masterbatch composition is then physically blended with additional biodegradable thermoplastic polymer and extrusion processed into final articles such as blown and cast films, molded products, and the like.

  • Patent number: 7217749
    Abstract: A process for rapidly infusing a synthetic resinous substrate with an alkali metal nitrite, comprises (a) essentially completely dissolving the alkali metal nitrite in supercritical carbon dioxide to form a solids-free solution having from about 1 to 15% by weight of the alkali metal nitrite; (b) contacting the synthetic resinous substrate with the solution for a time sufficient to transfer at least a portion of the alkali metal nitrite into the synthetic resinous substrate while maintaining the carbon dioxide under supercritical conditions; and, (c) decreasing pressure or temperature, or both, on the synthetic resinous material sufficiently to evolve carbon dioxide and leave micronized solid alkali metal nitrite crystals in an amount less than 2% by weight essentially uniformly distributed in the synthetic resinous substrate.

  • Patent number: 7217750
    Abstract: The present invention relates to various processes that utilize one or more supercritical fluids to disperse various inorganic and organic materials, including crystalline materials, into polymeric compositions, substrates or pre-formed articles without the utilization of melt processing of the polymeric compositions or exposing the various inorganic and organic materials and the polymers (or polymeric precursors) to a hot environment. The present invention also describes the unique properties that can be imparted to a polymer/resin composition or article once it has been subjected to a process according to the present invention versus those normally attributable to conventionally treated/processed polymer materials.

  • Publication number: 20060062994
    Abstract: A metal article is coated with a thick liquid film of a corrosion inhibiting, substantially anhydrous composition having a pH in the range from 6 but less than 8, containing less than 10 wt % of an ester of a vegetable oil and less than 2 wt % of a known corrosion inhibitor (“CI”) which is required to be at least partially soluble in a solvent which is driven off. The resulting solvent-free ester has a high concentration of CI and coats the surface of a metal part with a thin, essentially invisible, protective oily film which is less than 15 ?m thick containing from 10 to 50 wt % of the CI homogeneously dispersed in the film. Depending upon the choice of CI in the protective oily film it may function only as a contact corrosion inhibitor (“CCI”), or the film-coated metal article may function as a vapor corrosion inhibitor (“VCI”), effective VCI over a period from about 4 weeks to 1 year. Such a metal article functions as a VCI, and the article is also protected by the film as a CCI.

  • Publication number: 20040173779
    Abstract: A biodegradable polymer (“biopolyrner) filled with more than 5 wt %, and up to about 35 wt % of an inert particulate filler so as to have a WVTR in the range from at least twice to about 50 times greater than that of low density PE having a melt flow index of 1 g/10 min, each of the same thickness, is more effective to protect metal parts against corrosion than “neat” or unfilled biopolymer. Moreover a cross-section of the filled biopolymer 0.025 mm thick, is substantially transparent if the neat biopolymer is transparent. The improvement in corrosion protection is obtained without decreasing the tensile strength of the film below a critical tensile strength of 2000 psi in either the machine or transverse direction, preferably in both directions, due to the uniformity of the dispersed particles in the filled biopolymer. Such uniformity is obtained because the ingredients in the biopolymer are essentially anhydrous.
