Abstract:
Ethylene-acrylic acid type interpolymer compositions and films having increased slip and reduced block. A compositionally uniform interpolymer is compounded with at least one amide additive of the formula R. sub. 1 --CO--NH--R. sub. 2 in which R. sub. 1 is selected from saturated alkyl groups having from 13 to 25 carbon atoms and mono-olefinically unsaturated alkyl groups having from 17 to 23 carbon atoms and in which R. sub. 2 is selected from saturated alkyl groups having 14 to 26 carbon atoms and mono-olefinically unsaturated alkyl groups having from 18 to 24 carbon atoms; and optionally, finely divided inorganic. In another embodiment, a compositionally uniform or a compositionally non-uniform interpolymer is compounded with: (i) about 0. 025-1 weight percent of saturated secondary fatty acid amide; (ii) about 0. 025-1 weight percent of unsaturated or mixed unsaturated secondary fatty acid amide; and optionally (iii) about 0. 025-1.
