| 20090247725 | Methods for Preparing Oxydiphthalic Anhydrides, Oxydiphthalic Anhydrides Prepared Thereby, and Polyetherimides Derived Therefrom - a method for preparing an oxydiphthalic anhydride comprises contacting, under reactive and substantially anhydrous conditions in a reactor, at least one halophthalic anhydride containing more than 250 ppm chlorophthalide impurity with a carbonate of the formula M | 10-01-2009 |
| 20090247727 | Method of Purifying Dianhydrides, the Dianhydrides Formed Thereby, and Polyetherimides Formed Therefrom - A method for purifying an oxydiphthalic anhydride comprises diluting a first mixture comprising an oxydiphthalic anhydride, a solvent, a catalyst, and an inorganic salt with a solvent, to provide a second mixture having a solids content of 10 to 30 percent based on total weight of the second mixture; filtering and washing the solids of the second mixture at a temperature below the crystallization point temperature of the oxydiphthalic anhydride to provide a third mixture; hydrolyzing the third mixture by adding water and a water-soluble acid to form a fourth mixture; heating the fourth mixture; then cooling to provide a solid-liquid mixture, optionally decanting a portion of the liquid, rediluting the remaining solid-liquid mixture, then filtering to provide a solid component; washing the solid component with water to provide a fifth mixture of oxydiphthalic tetraacid and water; ring closing the oxydiphthalic tetraacid to provide oxydiphthalic anhydride, and filtering the oxydiphthalic anhydride. | 10-01-2009 |
| 20100160578 | PROCESS FOR CONTROLLING REACTION STOICHIOMETRY DURING POLYMERIZATION OF THERMOPLASTIC RESINS - The present invention provides a process for measuring and controlling chemical reactions that produce thermoplastic polymers by utilizing a stoichiometry correction during a reaction cycle to produce thermoplastic resins with desired properties. The thermoplastic polymer is made from at least one first monomer having a first reactive end group and at least one second monomer having a second reactive end group by reaction of the first reactive end group with the second reactive end group and has a glass transition temperature of greater than 130° C. | 06-24-2010 |

| 20090029615 | Crystallizable Polyetherimides, Method of Manufacture, and Articles Derived Therefrom - A composition is described, which comprises a crystallizable polyetherimide derived from the polymerization of: (a) a dianhydride component, comprising more than 96.8 mole % of 4,4′-bisphenol A dianhydride or a chemical equivalent thereof; and (b) a diamine component comprising a diamine or a chemical equivalent thereof, wherein the crystallizable polyetherimide has a T | 01-29-2009 |
| 20090099300 | METHODS OF MAKING POLYMER BLEND COMPOSITIONS - Methods of making miscible and compatible immiscible polymer blends are disclosed. The polymer blends have a polyimide as a component. The miscible polymer blends have a single glass transition temperature. The compatible polymer blends have two glass transition temperatures. The polymer blends may optionally include one or more fillers. | 04-16-2009 |
| 20090292128 | PRODUCTION OF LOW COLOR POLYETHERIMIDES - The production of low color polyetherimides, including its intermediates, such as bisimides and diaryl diether dianhydrides, may be affected by producing an improved purity intermediate of 4-nitro-N-alkylphthalimide. A salt, such as alkali metal carbonate or alkali metal hydrogen carbonate, is added to an aqueous mixture of 4-nitro-N-alkylphthalimide and 3-nitro-N-alkylphthalimide to selectively hydrolyze the imide linkage of 3-nitro-N-alkylphthalimide forming a water-soluble acid-amide salt. An organic solvent is added to this salt mixture to phase separate 4-nitro-N-alkylphthalimide having dissolved in the organic solvent from acid-amide salt of 3-nitro-N-alkylphthalimide having dissolved in water. | 11-26-2009 |
