    摘要： Polymeric carbon can be formed by a method comprising the steps of(a) polymerizing 1-bromo-4-lithiobenzene to form a brominated polyphenylene wherein the ratio of brominated to non-brominated residues in the polymer is 1:5 or greater;(b) functionalizing the brominated polyphenylene to replace the bromide groups with a substituted or unsubstituted acetylene group; and(c) heating the functionalized polymer to a temperature of 900.degree. C. to form polymeric carbon. Preferably, the brominated polyphenylene is formed in an ethereal solvent such as tetrahydrofuran and then functionalized using a palladium catalyst and a copper catalyst. When the acetylene substituent is phenylacetylene, the product of the method is glassy carbon.

    摘要翻译： 聚合碳可以通过包括以下步骤的方法形成：（a）聚合1-溴-4-锂苯以形成溴化聚亚苯基，其中聚合物中溴化与非溴化残基的比例为1:5或更大; （b）用取代或未取代的乙炔官能化溴代聚亚苯取代溴基; 和（c）将官能化聚合物加热到900℃的温度以形成聚合碳。 溴代聚亚苯基优选在醚溶剂如四氢呋喃中形​​成，然后使用钯催化剂和铜催化剂进行官能化。 当乙炔取代基是苯基乙炔时，该方法的产物是玻璃碳。

    摘要： Colorant compositions are useful for a wide variety of product applications. For example, colorants are used in tinting of polymers, providing colors to aqueous solution(s), and affording color to solid or semi-solid products such as detergents. Disclosed herein are colorant compositions having a triphenylmethane (“TPM”) structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels.

    摘要： Colorant compositions are useful for a wide variety of product applications. For example, colorants are used in tinting of polymers, providing colors to aqueous solution(s), and affording color to solid or semi-solid products such as detergents. Disclosed herein are colorant compositions having a triphenylmethane (“TPM”) derived structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels. The colorant compositions of the invention are useful as applied in polyolefins, such as polypropylene and polyethylene, as examples. These colorant compositions also may be employed in thermoplastics, such as PET, for example.
