PURPOSE:To improve the antistatic properties by dispersing a specified aromatic polycarbonate copolymer in a plastic material. CONSTITUTION:An aromatic polycarbonate having a quantity of static charge build-up of below 50mV, a quantity of dynamic charge build-up of 150mV or less, and a viscosity-average molecular weight of 1.5X10<3> to 5.0X10<4> and preferably consisting of 4,4'-dihydroxy-2,2,2-triphenylethane units and 1,1'-bis-(4- hydroxyphenyl)-m-diisopropylbenzene units is dispersed in a plastic material. |
