摘要： A method for making an amine-terminated polyarylene polyether thermoplastic in which a liquid/solid slurry reaction mixture is formed in an oxygen-free atmosphere. The reaction mixture is composed of a dihydroxyaromatic compound, a dihaloaromatic compound, an amino-hydroxyaromatic compound, a weak base, an aprotic polar solvent and a non-aromatic azeotrope former which is substantially imiscible with the aprotic polar solvent, said azeotrope former consisting of a molecule which has from 6 to 10 carbon atoms. The reaction mixture is refluxed at an elevated temperature to eventually produce a solution of the amine-terminated polyarylene polyether in the polar solvent. The method is designed for use in producing large amounts of thermoplastic in a simple, efficient and reliable manner.

摘要： Electrically conductive compositions of carbon nparticles having thin coatings of conductive polymer are disclosed. The thin coatings of conductive polymer electrically interact with each carbon particle and protect the carbon particles from conductive failure. Because the conductive compositions of coated carbon particles maintain their conductive characteristics even after long term exposure to chemicals, they are useful as filler materials in polymer compositions utilized to fabricate chemical delivery devices.
