ABSTRACT:
Oriented polyolefin (especially polypropylene) film having antistatic properties is produced by applying to the cast extrudate an aqueous solution of an `Ethoquad` salt (e.g. `Ethoquad` C/12) before heating and stretching the extrudate to orient it. The corresponding tertiary amine chlorides (e.g. prepared from `Ethomeen` T/12) are not effective.
