Title:
SEMICONDUCTIVE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP3766153
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a semiconductive resin composition reduced in a dispersion of volume resistivity and undergoing very little change in volume resistivity upon the repeated application of a high voltage by mixing a fluororesin having a specified relative permittivity with an alkali metal sulfonate or alkali metal carboxylate of a perfluroalkyl compound and an inorganic alkali metal salt in a specified ratio.
SOLUTION: This composition comprises 100 pts.wt. fluororesin having a relative permittivity of 3 or above (at 1kHz and 23°C), 0.01-5 ptw.wt. alkali metal sulfonate or alkali metal carboxylate of a perfluoroalkyl compound and 0.01-1 pt.wt. inorganic alkali metal salt. The fluororesin is desirably a vinylidene fluoride resin. The composition is desirably one in which the alkali metal sulfonate or carboxylate of the perfluoroalkyl compound is potassium sulfonate of a perfluoroalkyl compound and is used in an amount of 0.03-1 pt.wt. per 100 pts.wt. fluororesin.
