The property of 101 kinds of surface active agents as internal antistatic agents for resins was studied. Surface active agents were kneadered into resin sheets by extruding. Evaluation was made from the view points of extrudability, thermal stability (discoloring), bleeding out and surface resistivity.<BR>Extrudability and bleeding out are closely related to compatibility with plastic resins. Results showed that all water-soluble surface active agents in this experiment had not good compatibility with resins, being very difficult for the incorporation into resins, and even in the case of the minimum concentration added they continued to bleed out until sticky. Thermal stability of amphoteric surface active agents (Na salts) and cationic surface active agents was very inferior, while that of anionic and nonionic surface active agents was good, but the latter had not good antistatic property except amine ethyleneoxide adducts. Neverthless, severe bleeding out of amine ethyleneoxide adducts makes them not commercially available.
