Abstract:
An antistatic resin composition, comprising: (a) 7-100 wt. parts of a graft copolymer formed by graft-polymerizing an ethylenically unsaturated monomer onto a rubber trunk polymer having an alkylene oxide group via an ester bond which rubber trunk polymer has been obtained by using a carboxylic acid salt surfactant as an emulsifier for polymerization, said graft copolymer having been recovered by acid precipitation, (b) 0-93 wt. parts of a thermoplastic resin, and (c) 0.1-5 wt. parts of an anionic surfactant having a thermal weight loss initiation temperature (as defined by JIS K7120) of at least 250Â° C.; wherein the rubber trunk polymer occupies 5-80 wt. parts within 100 wt. parts in total of (a) and (b).
