Patent number: 5095076Abstract: Preparation of conductive polymers, particularly polyanilines having good solubility in organic solvents and high electrical conductivity, by providing a mixture of aniline, dianiline and a flexible diamine such as 1,3-bis (3-aminophenoxy)benzene or triethylene tetramine. The mixture is reacted in the presence of an oxidant such as ammonium persulfate and a protonic (Bronsted) acid, e.g. tosic acid, to polymerize the mixture and form a conductive polyaniline in which the conjugation is interrupted by an intermediate diamine group, and which renders the resulting polymer more flexible than polyaniline per se. The conductive polymer so produced also has terminal primary amino groups which aid solubility and which are further reactive. The conductive polyaniline product of the invention can be blended with non-conductive resins such as polyimides to provide cured conductive resin blends having good mechanical properties.Type: GrantFiled: November 5, 1990Date of Patent: March 10, 1992Assignee: Lockheed CorporationInventors: Sandra K. Clement, Deanne P. Yamato, Randy E. Cameron

Patent number: 4785073Abstract: A series of melamine-phenol-formaldehyde resoles for pressure-free to low pressure, low/medium temperture conversion into moulded product. The molar ratio of melamine:phenol is the range 1:4.7 to 1:0.29; for each mole of melamine there are 1.5 to 3 moles of formaldehyde; and for each mole of phenol there are 1.2 to 2 moles of formaldehyde. The resin compositions may contain fillers/reinforcing fibers, glycols and water curing is at or near neutal pH and may be accelerated by the use of boric oxide or acid and also by microwave heating. Moulded products have good heat-and fire-resistance, and good smoke emission properties, and are non-toxic.Type: GrantFiled: April 11, 1985Date of Patent: November 15, 1988Assignee: Polymer Tectonics LimitedInventors: Robert Farkas, Lothar M.
