The slip and/or block characteristics of ethylene interpolymers with acrylic or methacrylic acid or ionomers thereof are improved by incorporating at least one secondary fatty acid amide having at least one unsaturated alkyl group. The amides are of the formula: R CONHR min wherein: R is C13 - C25 saturated alkyl or C17- C23 mono-olefinically unsaturated alkyl, and R min is C14 - C26 saturated alkyl or C18 - C24 mono-olefinically unsaturated alkyl C18 - C24 mono-olefinically unsaturated alkyl provided that: (a) when both R and R min are saturated alkyl, there also is present an unsaturated or mixed unsaturated secondary amide of said formula (i.e. in which at least one of R and R min is unsaturated alkyl), (a) when both R and R are saturated alkyl, there also is present an unsaturated or mixed unsaturated secondary amide of said formula (i.e. in which at least one of R and R min is unsaturated alkyl), (b) when R is unsaturated alkyl and R min is saturated alkyl, there also is present a saturated, or unsaturated amide of said formula or a mixed unsaturated secondary amide of said formula in which R is saturated alkyl and/or R min is unsaturated alkyl (c) when R is unsaturated C17-C18 alkyl and/or R min is unsaturated C18-C19 alkyl, the interpolymer is compositionally uniform, and (d) when R is saturated alkyl and R min is unsaturated alkyl, the interpolymer is randomly compositionally uniform. u
