发明人：KELLER TEDDY M; LASKOSKI MATTHEW
权利人:US NAVY
摘要:A cyanate ester system is disclosed. An aryl ether oligomer may be made from a dihydroxyaromatic compound and a dihaloaromatic compound in the presence of a base. The oligomer is then reacted with a cyanide compound in the presence of a base to form the cyanate ester shown below. The cyanate ester may then be cross-linked to a thermoset having triazine ring cross-links.n nHO—Ar 2 O—Ar 1 —O—Ar 2 n OH

标 题 :Synthesis of phenolic monomers containing imide or diimide moieties and high heat carbonate polymers prepared therefrom
发明人：AMERIK VALENTINA; HOEKS THEODORUS L; LIKIBI PARFAIT JEAN MARIE; NELSON MARK
权利人:GEN ELECTRIC
摘要:A process has been surprisingly discovered that can produce a high heat carbonate polymer (i.e., one with a Tg greater that 150° C.), without the drawbacks encountered in attempts to produce a high heat carbonate polymer. The process of the instant invention comprises the steps of: n (1) reacting an aromatic amine with a dihydric phenol to prepare an aminophenol; n (2) reacting an anhydride or dianhydride with the aminophenol to prepare a phenolic precursor; and n (3) reacting the phenolic precursor with a carbonate precursor to prepare a high heat carbonate polymer.

标 题:Process for synthesis of polyestercarbonate-siloxane copolymers
发明人：HAWKINS CHRISTOPHER M; ROSENQUIST NILES R
权利人:GEN ELECTRIC
摘要:A process for synthesizing polyestercarbonate-siloxane copolymers which have a smaller concentration of low molecular weight species and greater thermal stability has been described. Essentially the process includes adding the comonomer, diacid chloride siloxane, after approximately 1/3 of the phosgene has been added, in a conventional interfacial copolymerization, (as opposed to addition at the beginning of the polymerization).

标题:Direct polymer templating synthesis of mesoporous carbon
发明人：DAI SHENG; NELSON KIMBERLY M
权利人:UT BATTELLE LLC; UNIV TENNESSEE RES FOUND
摘要:The invention is directed to a method for fabricating a mesoporous carbon composite material. The method comprises providing a precursor composition and subjecting the precursor material to a curing step followed by carbonization step. The precursor composition comprises (i) a templating component comprised of a linear homopolymer material, (ii) a phenolic compound or material, (iii) a crosslinkable aldehyde component, and (iv) an acid catalyst.

标题:Processes for the synthesis of dentritic macromolecules from conventional monomers
发明人：PERCEC VIRGIL
权利人:UNIV PENNSYLVANIA
摘要:The inventive subject matter relates to novel synthetic processes which use a multifunctional compound (the “TERMINI compoundâ€?) having a masked or protected functional group, wherein the TERMINI compound is capable of quantitatively and irreversibly interrupting a living polymerization or a chain organic reaction. After deprotection or demasking of the functional group of the TERMINI compound, the same living polymerization or organic reaction resumes with 100% efficiency, or a different living polymerization or organic reaction resumes with 100% chemoselectivity, respectively. Once incorporated into a growing molecule, the TERMINI compound generates a branching point upon resumption of the polymerization or reaction.
