  • Patent number: 6740731
    Abstract: The present invention is directed to a method for reducing waste accumulation by using an environmentally degradable disposable material. The disposable material, which includes a hydroxycarboxylic acid-containing polymer, degrades hydrolytically during operative and disposal stages in a controlled manner such that the disposal degradation rate of the material is accelerated relative to the operative degradation rate of the material.
    Type: Grant

  • Patent number: 6418642
    Abstract: Disclosed is a slipper having an outsole, an insole and an upper attached to the outsole. The outsole includes a bottom wall and a perimeter wall extending from the bottom wall to provide a polymer insole jell receiving area. The insole includes a polymer insole jell and is provided within the polymer jell insole receiving area of the outsole. The polymer insole jell can be formed within the polymer insole jell receiving area, or the polymer insole jell can be preformed and placed within the polymer insole jell receiving area. Also disclosed is a method for manufacturing a slipper.

  • Patent number: 5470945
    Abstract: Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. Aromatic polyimide, aromatic polycarbonate, polyarylsulfide, aromatic polyester with liquid crystal property, and polyarylimidazolidine oligomers are incorporated into the isocyanate or labile hydrogen compounds to give high-performance characteristics. Such thermally-reversible isocyanate-based polymer compositions with high-performance characteristics are useful, among other things, as finish surface coatings on composite materials such as polypropylene and polyethylene terephthalate. Novel phenolic-hydroxyl terminated polyarylsulfide and polyarylimidazolidine oligomers and their preparation are also described.

  • Patent number: 5451439
    Abstract: Mixtures of styrene-isoprene block copolymer and ultralow density polyethylene are provided as moldable rubber substitutes. These mixtures may be used in the production of electrical lineman's gloves and other flexible items such as other types of gloves, tubing, balloons, condoms, toys, inflatable liners, baby nipples, and rubber bands.

  • Patent number: 5387667
    Abstract: Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. High-performance characteristics are incorporated into the polymer by using aromatic polycarbonate, aromatic polyester, polyarylsulfide, and polyarylimidazolidine oligomers. The compositions are useful as hot-melt adhesives, coatings and especially finish surface coatings on composite materials such as polypropylene and polyethylene terephthalate, moldings and in injection reaction molding applications and composite and laminate fabrication.
