    Abstract: There is provided a treatment method of efficiently separating an additive component from a resin component for the purpose of treating and recycling a thermoplastic resin composition containing an additive. The treatment method includes heating and agitating the thermoplastic resin composition containing the additive together with a solvent for dissolving at least part of the additive at a temperature ranging from the glass transition temperature of the thermoplastic resin to the boiling point of the solvent inclusive, and separating and recovering the solvent in a liquid state in which at least part of the additive is dissolved, so that at least part of the additive is separated and removed from the thermoplastic resin composition.

    Abstract: A flame retardant thermoplastic resin composition comprises a thermoplastic resin comprising a polyphenylene ether resin, a high impact polstyrene resin or an acrylonitrile-butadiene-styrene resin; an organo phosphate compound in an amount less than or equal to about 20 parts by weight for every 100 parts by weight of the thermoplastic resin; and a polyhydric alcohol compound in an amount of about 0.5 to about 5.0 parts for every 100 parts by weight of the thermoplastic resin. A method for the manufacture of the thermoplastic resin composition is also disclosed. The thermoplastic resin composition exhibits high flow characteristics and improved impact strength while providing effective flame retardance.

    Abstract: This invention relates to improvements in preventing heat- and moisture-shrink problems in specific polypropylene fibers. Such fibers require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the nullrigidifyingnull nucleator compounds provide nucleation sites for polypropylene crystal growth. After drawing the nucleated composition into fiber form, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred nullrigidifyingnull compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2null-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11). Specific methods of manufacture of such fibers, as well as fabric articles made therefrom, are also encompassed within this invention.

    Abstract translation: 本发明涉及防止特定聚丙烯纤维中的热收缩和水分收缩问题的改进。 这种纤维需要某些化合物的存在,这些化合物在热定型之后快速且有效地为目标聚丙烯纤维提供刚性。 通常,这些化合物包括在暴露于足够的热量以熔化初始颗粒状聚合物之后和允许这样的熔体冷却时使目标聚丙烯中的聚合物晶体成核的任何结构。 在冷却期间,化合物必须在比没有成核剂的目标聚丙烯更高的温度下使聚合物晶体成核。 以这种方式,“硬化”成核剂化合物提供聚丙烯晶体生长的成核位点。 将成核组合物拉制成纤维形式后,然后将纤维暴露于足够的热量以生长结晶网络,从而将纤维保持在所需位置。 优选的“硬化”化合物包括二亚苄基山梨醇基化合物,以及较不优选的化合物,例如苯甲酸钠,某些钠和磷酸锂盐(例如2,2'-亚甲基 - 双 - (4,6-二 - 叔丁基苯基)磷酸酯,也称为NA-11)。 制造这种纤维的具体方法以及由其制成的织物制品也包括在本发明内。

    Abstract: The invention relates to methods for obtaining the photochromic latex comprising the polymerization in aqueous emulsion of an initial polymerizable mixture, comprising one or more monomers polymerizable by free-radical mechanism and one or more photochromic compounds and the addition to the initial polymerizable mixture, during the polymerization of the initial polymerizable mixture or to the final latex of at least one agent for stabilizing the photochromic properties. Such latexes can be used in the production of photochromic films. Such films may be used, for example, on optical lenses.
