  • Patent number: 7358323
    Abstract: A water-soluble, flame retardant polyester resin is obtained by a condensation reaction or a polycondensation reaction of a dicarboxylic-acid component, a glycol component, a water-solubility imparting component and a reactive phosphorus-containing compound such that a ratio of the water-solubility imparting component in a total of the dicarboxylic-acid component and the water-solubility imparting component is in a range of 1 to 60 mol %. Since this polyester resin can be dissolved in a solvent by allowing a halogen-free, phosphorus-containing polyester with excellent flame resistance to have water solubility, it is possible to improve applicability and eliminate problems of working environment and environmental destruction resulting from organic solvents. In addition, even when treating substrates such as fibers and PET films with the polyester resin, there is no deterioration of these substrates.

  • Patent number: 6590067
    Abstract: 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.
