Abstract: The invention relates to an oriented film of ABS composition comprised of a resin and a rubber phase, which film exhibits little or no haze, does not stress- or crease-whiten, and has improved low-temperature impact properties. The film is oriented at a temperature below the glass transition temperature of the resin phase. It is preferably biaxially oriented.

Abstract: Azidoformyl compounds containing a hindered phenolic antioxidant moiety have been found to provide built-in antioxidant protection. They add to and protect polymers, including saturated, unsaturated, linear, crystalline and non-linear-amorphous hydrocarbon polymers, copolymers, terpolymers, etc., including especially polyethylene, polypropylene, polystyrene, and the rubbers, such as natural rubbers, polybutadienes, polyisoprenes, butadiene-isoprene copolymer, butyl rubber, ethylene-propylene copolymer, ethylene-propylene-dicyclopentadiene terpolymer, etc. and blends thereof.
