    Abstract: This invention presents polymers and copolymers comprising repeating units of thieno[3,4-b]thiophene. Water-borne dispersions of such polymers and copolymers can be cast by conventional methods to provide uniform, thin films which possess utility in numerous electroactive applications including electrochromic displays, optically transparent electrodes and antistatic coatings. The compositions of this invention can be doped with conventional p-dopants or n-dopants. The invention also presents an aqueous process for preparing such compositions of matter.

    Abstract: Polyurethane prepolymer which can be converted into a final product by reaction with a curative or chain extending agent is made by reacting polyisocyanate with polyol in the presence of an amount of an aliphatic hydrocarbon which is a solvent for the polyisocyanate but a non-solvent for the prepolymer. In order to minimize the formation of unwanted oligomers the polyisocyanate is present in stoichiometric excess with respect to the polyol and the amount of hydrocarbon solvent present in the reaction mixture is limited so that a single liquid phase is present in the mixture during most of the synthesis. Solvent containing dissolved isocyanate is then removed from the prepolymer by liquid phase separation. A portion of the solvent can be distilled from this isocyanate solution for use in liquid--liquid extraction of residual isocyanate from the prepolymer, and the remaining solution of isocyanate in hydrocarbon solvent can be used in prepolymer synthesis. A preferred method of liquid--liquid extraction of unreacted polyisocyanate from prepolymer is by counter-current flow of the prepolymer and hydrocarbon solvent through a vertically elongated contact column. This technique can be used independently or in combination with the use of hydrocarbon solvent in the prepolymer synthesis.

    Abstract: Hybrid polymeric compositions of epoxy resin and vinyl acetate polymer are combined in an aqueous emulsion also containing an emulsifying agent and isophoronediamine as a hardener for the epoxy resin. The emulsion is stable for long periods of time but can be cast and cured at room temperature, providing a one-pot system for the preparation of protective coatings, laminating adhesives, and the like. The vinyl acetate polymer must be emulsion polymerized independently of the epoxy resin and is preferably a copolymer of vinyl acetate with ethylene or n-butyl acrylate. The pot life of these hybrid polymer emulsions containing the epoxy hardening agent is at least one month and frequently as long as a year.
