Abstract

Coating compositions and molding compositions containing an amount of alkyl vinyl ether polymer which is effective for improving leveling and/or preventing or eliminating foam, and the use of these copolymers for improving leveling and/or preventing or eliminating foam in coating compositions and molding compositions. The alkyl vinyl ether polymer is a copolymer containing identical or different repeating units of the formula ##STR1## in which R represents a C.sub.1-18 --alkyl group or C.sub.m F.sub.2m+1 --(CH.sub.2).sub.2 --group, where m is a number from 4 to 18, and identical or different repeating units of the formula ##STR2## in which R' represents various groups.
