ABSTRACT:
Polyolefin foams and films having improved electrostatic properties are provided by incorporating into the polyolefin foam or film a novel antistatic additive composition comprising 0.1 to 10 parts per hundred based on the weight of the olefin polymer of a quaternary ammonium salt and 0.1 to 10 parts per hundred based on the weight of the olefin polymer of a partial ester of a long-chain fatty acid with a polyol. A method of making the foam containing the novel antistatic additive composition is also disclosed.
