Abstract:
1. A semiconductive polyvinylidene fluoride resin composition comprising 100 parts by weight of a polyvinylidene fluoride resin (A), 0.03 to 10 parts by weight of at least one quaternary ammonium salt (B) selected from the group consisting of tetraalkylammonium sulfates (B 1 ) represented by the formula (1): wherein R 1 to R 4 are alkyl groups which are the same or different from one another, and R 5 is an alkyl or fluoroalkyl group or a hydrogen atom, and tetraalkylammonium sulfites (B 2 ) represented by the formula (2): wherein R 6 to R 9 are alkyl groups which are the same or different from one another, and R 10 is an alkyl or fluoroalkyl group or a hydrogen atom, and 2 to 15 parts by weight of at least one conductive carbon black (C) selected from the group consisting of acetylene black and conductive oil furnace black and having a DBP oil absorption of at least 100 ml/100 g, and wherein the semiconductive polyvinylidene fluoride resin composition has a volume resistivity within a range of 10 4 to 10 12 Ωcm.
