Abstract

A resin composition having excellent antistatic properties and practical physical properties. The resin comprises (i) a styrene resin; (ii) a polyethylene oxide having a viscosity-average molecular weight ranging from 15,000 to 1,200,000; (iii) either or both of a (meth) acrylate resin and an oxide selected from the group consisting of titanium oxide, zinc oxide and magnesium oxide; (iv) either a surfactant selected from specific sulfonic acid salts or a surfactant selected from specific alkyl sulfates; and, optionally, (v) a (poly)ethylene glycol having an average molecular weight ranging from 62 to 1,200. The resin composition also provides excellent resistance to hot water.
