标 题:Synthesis of porous carbon-based materials from expanded polystyrene
发明人：SAHA DIPENDU; GRAPPE HIPPOLYTE A
权利人:Eco Carbon LLC
摘要:A process for synthesizing a carbon molecular sieve and an activated carbon from expanded polystyrene is provided. The process includes sulfonating the expanded polystyrene with sulfuric acid in the presence of a solvent, for example, chloroform, to obtain sulfonated polystyrene; carbonizing the sulfonated polystyrene to obtain a carbon molecular sieve (CMS) with a substantially high degree of porosity; and activating the CMS by adding an activating agent to the CMS to obtain an activated carbon with a substantially high degree of porosity. The activating agent is selected from one or more of steam, potassium hydroxide, carbon dioxide, zinc chloride, phosphoric acid, sodium carbonate, aluminum chloride, magnesium chloride, and sodium hydroxide. A low temperature of, for example, about 50 degrees Celsius, is employed for sulfonating the expanded polystyrene. Heating and cooling operations in the steps of synthesizing and activating the CMS are performed under a nitrogen gas atmosphere.

摘要:Various embodiments provide random copolyimides that may possess the mechanical, thermal, chemical and optical properties associated with polyimides yet achieve a low energy surface. In various embodiments, the copolyimides may be prepared using a minor amounts of a diamino terminated fluorinated alkyl ether oligomer and a diamino terminated siloxane oligomer. The various embodiments include processes for making the copolyimides containing fluorine and silicon surface modifying agents and anisotropic coatings and articles of manufacture from them. Thus the coatings and articles of manufacture made with the copolyimides of the various embodiments may be characterized as having an anisotropic fluorine and silicon composition and low surface energy.

标题:Process for nucleophilic derivatization of materials having an imide group conjugated to an aromatic moiety
发明人：GOLDBERG MARTIN J; MORRIS DANIEL P; VIEHBECK ALFRED
权利人:IBM
摘要:A process for the synthesis of derivatives of materials containing an imide group conjugated to an aromatic moiety to form an ester, a thioester, an amide, a ketone, and silylesters. Electrons are supplied to redox sites to form a reduced imide material. The reduced imide material is contacted with a nucleophile which opens the imide ring of the reduced imide and chemically combines with a carbonyl carbon atom of the open imide ring to form an imide derivative.
