Abstract : The report presents results of a search for polymeric materials which theoretically could function as superconductors at elevated temperatures. Among the several thousand ploymeric materials which one can expect to be electronically conductive, the authors have to date, examined some 95 for evidence of superconduction. Of those, none were superconducting, but several were found which were very highly conductive, exceeding graphite and packed copper powder in conductivity, and increasing in conductivity as the temperature was lowered. Many others which were quite conductive were found. Many materials were found which displayed a new and very intense dielectric polarization (hyper-electronic polarization). Dielectric constants up to 300,000 are being shown by these organic solid materials. New synthetic procedures for conducting polymers were uncovered. Unique equipment capable of detecting superconduction magnetically and conductively at cryogenic temperatures and at extreme pressure was developed here and is now in use. (Author)
