Abstract

The invention relates to mixtures comprising A) a copolymer of lower olefins and vinyl esters, comprising a) from 65 to 94 mol% of divalent structural units of the formula 1 -CH2-CR1R2- 1 in which R1 and R2, independently of one another, are hydrogen or methyl, b) from 1 to 25 mol% of divalent structural units of the formula 2 (see Formula 2) in which R3 is saturated, branched C6-C16-alkyl which contains a tertiary carbon atom, and c) from 5 to 35 mol% of divalent structural units of the formula 3 (see Formula 3) where the sum of the molar proportions of comonomers of the formulae 2 and 3 is between 6 and 35 mol%, and at least one of the following components B1) to B3): B1) a further copolymer as described under A), or B2) an ethylene-vinyl ester copolymer containing from 5 to 35 mol% of structural units derived from the vinyl ester, in addition to structural units derived from ethylene, or B3) an ethylene-vinyl ester-olefin terpolymer, wherein R3 is bonded to the carboxyl function via its tertiary carbon atom.
