    摘要: The present invention is directed to the preparation of frit pastes suitable for sealing together preformed glass parts, being especially suitable for sealing glass panels to funnels of cathode ray tubes. The pastes comprise a mixture of frit particles, a lacquer, and at least one additive in an amount of 0.0005-2% by weight total of the lacquer. The preferred additives are selected from the group of alkyl organic phosphate esters, a mixed titanium ortho ester complexes, and substituted sorbitols in the polyol acetal family.

    摘要: A process for forming a polyurethane dispersion containing polyhedral oligomeric silsesquioxane (POSS) nanoparticles, comprising reacting a POSS with a diisocyanate in the presence of acetone, reacting the resulting compound with a polyol and an ionic compound selected from the group consisting of an acidic diol or sodium sulfonate to form an isocyanate prepolymer chain, extending the isocyanate prepolymer chain by adding a diol, and forming an aqueous dispersion. Also, a polyurethane dispersion or film comprising a homogeneously distributed polyurethane bound POSS prepolymer.

    摘要: Method for making polymer particulates, such as spherical powder and whiskers, by melting a polymer material under conditions to avoid thermal degradation of the polymer material, atomizing the melt using gas jet means in a manner to form atomized droplets, and cooling the droplets to form polymer particulates, which are collected for further processing. Atomization parameters can be controlled to produce polymer particulates with controlled particle shape, particle size, and particle size distribution. For example, atomization parameters can be controlled to produce spherical polymer powders, polymer whiskers, and combinations of spherical powders and whiskers. Atomizing apparatus also is provided for atoomizing polymer and metallic materials.
