Patent number: 4933394Abstract: A material that includes an organic polymer capable of being rendered electrically conductive by electrochemical oxidation or reduction, and a redox compound ionically or covalently bonded to the polymer. The redox potential of the redox compound is more positive than the redox potential of the polymer when the polymer is electrically conductive in the oxidized state and more negative than the redox potential of the polymer when the polymer is electrically conductive in the reduced state.Type: GrantFiled: May 1, 1987Date of Patent: June 12, 1990Inventor: Joseph S. Foos

Patent number: 4912170Abstract: This invention relates to a p-methyl styrene polymer represented by the following formula: ##STR1## Z denotes a group such as a functional group. Poly p-methylstyrene (PPMS) is lithiated by reaction with n-butyllithium. The lithiated PPMS is used to prepare polymers containing functional groups. As an example, a solution of PPMS (MW 260,000), 1.0 g in 20 ml of cyclohexane, was reacted with n-butyllithium, 8.5 mmol, and tetramethylethylenediamine, 8.7 mmol, for 20 hours to obtain a precipitate. The precipitate was dissolved in THF, and CO.sub.2 was blown into the solution. The solution was washed with an aqueous solution of HCl and dropped into methanol to obtain a solid polymer having carboxyl group functionality.Type: GrantFiled: December 22, 1988Date of Patent: March 27, 1990Assignee: Toa Nenryo Kogyo K.K.Inventors: Tadashi Niwa, Masayuki Kato, Yoshio Taguchi, Chihiro Imai, Tokuo Makishima, deceased, by Nobuko Makishima, legal representative
