Abstract:
A process for the production of a molded article having positive temperature coefficient characteristics from a resin composition containing a crystalline resin, electrically conductive particles and an organic peroxide. A molded article having excellent PTC characteristics over that of a conventional molded article can be obtained by a process which comprises mixing the crystalline resin and the electrically conductive particles to obtain a mixture; crosslinking the crystalline resin with the organic peroxide by kneading the mixture under a shear force; and simultaneously or successively molding the resultant kneaded mixture.
