Abstract: The mixture of di-isocyanate , polyol and grinding chips was placed in a casting mold and magnetic field was applied by a pair of ferrite magnet to magnetize the grinding chips in the mixture. The mixture was set in a heated oven and the electrical resistance of the curing mixture was continuously measured It was found that the conductivity of the mixture developed with the cure of the resin and the rate of the development depends on the curing temperature and curing accelerator. The final conductivity of the cured products depends on the amount of grinding chips and the magnetization. It was found that the cured product having the resistivity of less than l.OΩ・cm can be prepared if 200phr of grinding chips is added, and magnetic field is applied to the prepolymer mixture. The use of curine accelerator and higher temperatures accelerate the curing reaction.
