Abstract: A method for removing volatile components from wet, solid polymeric materials on a vacuum vented extruder is described. Polymeric materials containing substantial amounts of water, 1-20 % by weight, are rapidly converted to polymer compositions containing less than about 0.5% by weight water at high throughput rates while avoiding complications resulting from excessive steam backflow through the extruder feed throat. The method utilizes a screw design comprising only forward flighted screw elements in an initial polymer melting and kneading zone. Steam generated as the polymer is heated and sheared flows downstream to a first vacuum vent for removal. The partially devolatilized polymer melt is then subjected to additional kneading and vacuum venting. The claimed method converts wet polycarbonate powder containing residual methylene chloride to essentially dry polycarbonate powder containing less than about 1 ppm methylene chloride.

Abstract: A particularly useful process which includes the steps of providing a feedstream comprising a soluble condensation promoting component capable of activating a heterogeneous acidic catalyst and a source of formaldehyde formed by conversion of dimethyl ether in the presence of a catalyst comprising silver as an essential catalyst component; and heating the feedstream with the heterogeneous acidic catalyst in a catalytic distillation column to convert methanol and formaldehyde present to methylal and higher polyoxymethylene dimethyl ethers and to separate the methylal from the higher polyoxymethylene dimethyl ethers is disclosed. Advantageously, methylal and higher polyoxymethylene dimethyl ethers are formed and separated in a catalytic distillation column. By including in the column an anion exchange resin, an essentially acid-free product is obtained which can be used directly as a blending component, or fractionated, as by further distillation, to provide more suitable components for blending into diesel fuel.

Abstract: A method of removing and reclaiming a double metal cyanide (DMC) catalyst from a polyol is disclosed. A polymeric acid that is soluble in the polyol is introduced into the polyol during or after the polymerization reaction. The polymeric acid reacts with the double metal cyanide catalyst thereby causing the double metal cyanide catalyst and the polymeric acid to form an agglomeration in the polyol. The agglomeration is easily separated from the polyol via filtration, for example. The recovered agglomerated DMC catalyst can then be reconstituted using an acid solution.

Abstract: Mixed alkali metal salts of phosphoric acid in combination with a co-catalyst such as tetramethylammonium hydroxide (TMAH) are excellent transesterification catalysts for use in the preparation of polycarbonate from bisphenol A and diphenyl carbonate. The mixed alkali metal phosphate salts were shown by kinetic measurements made on a model system composed of p-tert-octylphenol and bis(p-cumylphenyl) carbonate to be inherently more potent catalysts than salts of phosphoric acid comprising a single alkali metal ion. In addition to providing higher rates of polymerization, the new catalysts were shown to provide polycarbonates containing reduced levels of Fries rearrangement product relative to polymerization reactions catalyzed by conventional catalyst systems such as sodium hydroxide together with TMAH co-catalyst.

Abstract: The present invention provides an organic anti-reflective film composition suitable for use in submicrolithography. The composition comprises a compound of chemical formula 11 and a compound of chemical formula 12. The organic anti-reflective film effectively absorbs the light penetrating through the photoresist film coated on top of the anti-reflective film, thereby greatly reducing the standing wave effect. Use of organic anti-reflective films of the present invention allows patterns to be formed in a well-defined, ultrafine configuration, providing a great contribution to the high integration of semiconductor devices. wherein a, b, c, R′, R″, R1, R2, R3, and R4 are those defined herein.
