Patent number: 4617353Abstract: A chemical process is provided for forming an electrically conductive polymer blend in which polypyrrole is a minor component. The polypyrrole is formed from a pyrrole monomer, optionally substituted at the 3- and 4-positions. The process comprises forming a solution of a matrix polymer in an anhydrous liquid reaction medium, and, in situ, contacting pyrrole monomer with a polymerization initiator selected from the group consisting of anhydrous halides of iron, cobalt or nickel (Group VIII metal) at a temperature in the range from about -20.degree. C. to below about the boiling point of the solution, so as to form the polypyrrole in situ. The polypyrrole so formed contains a Group VIII metal halide counterion dispersed within the matrix polymer so as to produce a conductive polyblend having a conductivity in the range from about 1 to about 150 ohm.sup.-1 cm.sup.-1 ("S/cm" for brevity), or a semiconductor having a conductivity in the range from about 10.sup.Type: GrantFiled: October 7, 1985Date of Patent: October 14, 1986Assignee: The B. F. Goodrich CompanyInventor: Ronald E. Myers

Patent number: H1077Abstract: The present invention relates to a process for the viscosification of an aqueous liquid which includes the steps of forming a solvent system of an organic liquid or oil and a polar cosolvent, the polar cosolvent being less than about 15 weight percent of the solvent system, a viscosity of the solvent system being less than about 1,000 cps; forming an interpolymer complex of neutralized sulfonated polymer (water insoluble) and copolymer of styrene/vinylpyridine in the solvent system to form a solution, a concentration of the water insoluble interpolymer complex polymer in the solution being about 0.01 to about 0.5 weight percent, a viscosity of the solution being less than about 200 cps; and admixing or contacting said solution with about 5 to about 500 volume percent water, the water being immiscible with the organic liquid and the polar cosolvent and interpolymer complex transferring from the organic liquid to the water phase, thereby causing the water phase to gel (i.e., thicken).Type: GrantFiled: May 21, 1990Date of Patent: July 7, 1992Inventors: Dennis G. Peiffer, Robert D. Lundberg, Ilan Duvdevani
