  • Publication number: 20030073764
    Abstract: Certain thermoplastic additives (combinations of clarifying and nucleating compounds) that induce simultaneously low clarity and high nucleation efficacy are provided. Such additives include combinations of certain bicyclic salts (which by themselves induce very high nucleation efficacy) and thermoplastic clarifying agents, including certain dibenzylidene sorbitol acetals and derivatives (hereinafter collectively referred to as “DBSs”)(which alone provide very low haze measurements and thus highly desirable clarity characteristics). In comparison, other types of standard thermoplastic nucleators, such as sodium benzoate and sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl) phosphate provide relatively high peak crystallization temperatures, but do not combine synergistically with clarifiers, such as DBSs, to provide the same results as for the inventive combination of bicyclic salts and DBSs.

  • Patent number: 6515057
    Abstract: A method and product which provides a solid, non-powdered homogeneous form to liquid and low melting point solid compounds which facilitates stability, storage, dispersability and handling and which may be added directly to formulations requiring the liquid compound or low melting point solid compound. The liquid or low melting point solid ingredient is combined with a binder which is comprised of at least a wax and thermoplastic polymer. During the method of forming the product, both the binder and the liquid compound (or low melting point solid compound) pass through a liquid phase during which they are mixed. The product is then formed and cooled.

  • Patent number: 6515036
    Abstract: A method of recovering a decomposition product from a polyurethane, the method comprising the steps of thermally decomposing a polyurethane into a liquid containing a polyol and a urea compound which is soluble in the polyol, and solids containing a urea compound which is insoluble in the liquid in the presence of a polyamine compound at a temperature of 120 to 250° C.; removing the solids; hydrolyzing the residue with water retained at a high temperature of 200 to 320° C. and a high pressure; and recovering the resulting polyamine and/or polyol.

  • Patent number: 6391938
    Abstract: Light cured nail coatings that are applied to natural nails and/or artificial nail-tips for cosmetic purposes. An optional bond-enhancing compound can be used to strengthen the bond between the light curable coatings and the natural nail. Also, finishing compounds may be used to clean the surface of the uv curable coatings resulting in a high-gloss shine. The methods of applying uv-radiation curable nail coatings, bond-enhancing compounds, and finishing compounds to artificial nail-tips and natural nail are also discussed.
