  • Patent number: 5259991
    Abstract: An improved positively temperature-dependent organic resistor, which is basically a composite consisting of a matrix phase of a synthetic resin and a dispersed phase of electroconductive particles, can be prepared by compounding a crystalline synthetic resin, carbon black, an organosilane compound having at least one alkoxy or alkoxy-substituted alkoxy group in a molecule and an organic peroxide, shaping the resin composition into the form of a resistor and heating the shaped body in contact with an aqueous medium containing a hydrolysis-condensation catalyst for the organosilane compound. As compared with resistors prepared by conventional methods, the resistor obtained by the inventive method is highly stable in the resistivity even after many times of repeated voltage loading.
