Patent number: 6974855Abstract: The novel polyimides of this invention are derived from Diels-Alder cyclopolymerization of photochemically generated bisdienes with dienophiles, such as bismaleimides, trismaleimides and mixtures thereof with maleimide end-caps. Irradiation of one or more diketones produces two distinct hydroxy o-quinodimethane (photoenol) intermediates. These intermediates are trapped via Diels-Alder cycloaddition with appropriate dienophiles, e.g., bismaleimide and/or trismaleimides to give the corresponding polyimides in quantitative yields. When bismaleimides, trismaleimides or mixtures thereof with maleimide end-caps are used as the dienophile, the resulting polyimides have glass transition temperatures (Tg) as high as 300° C. Polyimide films can be prepared by ultraviolet irradiation of high solids content varnishes of the monomers in a small amount of solvent, e.g., cyclohexanone, dimethyl formamide, N-methylpyrollidone and the like.Type: GrantFiled: July 8, 2003Date of Patent: December 13, 2005Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Michael A.

Patent number: 6590067Abstract: A method for lateral chain modification of aryl main chain polymers with aromatic ketones or aldehydes containing tertiary basic N-groups is described. The modification can be accomplished via addition of an aromatic carboxylic acid or an acid derivative containing a tertiary amine moiety to a metallized polymer. The tertiary amines on the modified polymer can be converted to quaternary amines with halogen alkanes. Modification of the aryl main chain polymers with aromatic groups containing sulphonic acid radicals is also described. The polymers formed can be crosslinked and prepared for use in a wide variety of membrane technologies including ion exchange, dialysis, reverse osmosis, nanofiltration.Type: GrantFiled: February 12, 2001Date of Patent: July 8, 2003Assignee: Universitaet StuttgartInventors: Jochen Kerres, Andreas Ullrich, Thomas Haring

Publication number: 20020007038Abstract: Improved anti-reflective coating compositions for use in integrated circuit manufacturing processes and methods of forming these compositions are provided. Broadly, the compositions are formed by heating a solution comprising a compound including specific compounds (e.g., alkoxy alkyl melamines, alkoxy alkyl benzoguanamines) under acidic conditions so as to polymerize the compounds and form polymers having an average molecular weight of at least about 1,000 Daltons. The monomers of the resulting polymers are joined to one another via linkage groups (e.g., —CH2—, —CH2—O—CH2—) which are bonded to nitrogen atoms on the respective monomers. The polymerized compound is mixed with a solvent and applied to a substrate surface after which it is baked to form an anti-reflective layer. The resulting layer has high k values, improved etch rates, and can be formulated for both conformal and planar applications.Type: ApplicationFiled: May 30, 2001Publication date: January 17, 2002Inventors: Rama Puligadda, Runhui Huang
