    • 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.
    • 基本上由合成树脂的基质相和导电性粒子的分散相构成的复合体的温度升高的有机电阻可以通过将结晶性合成树脂,炭黑,至少具有以下的有机硅烷化合物 分子中的一个烷氧基或烷氧基取代的烷氧基和有机过氧化物,将树脂组合物成形为电阻体的形式,并加热与包含有机硅烷化合物的水解缩合催化剂的水性介质接触的成形体。 与通过常规方法制备的电阻器相比,通过本发明方法获得的电阻器在电阻率方面是高度稳定的,即使在多次重复的电压负载之后。
