This invention is concerned with an article comprising a polyolefin substrate and adherent thereto a vinyl addition polymer of monomers comprising at least 5% by weight a primary monomer selected from (a) monomers having the formula ##STR1## wherein X is --O--, --NH-- or --NR.sup.5 --; R.sup.1 and R.sup.7, individually, are H, methyl or ethyl; R.sup.2 is H or an organic radical, preferably --COOH, --CONH.sub.2 or --COOR.sup.6 ; R.sup.3 is H or an organic radical, preferably methyl, other alkyl having up to about five carbon atoms, --CH.sub.2 COOR.sup.6, --COOR.sup.6 or --CH.sub.2 COOH; R.sup.4 and R.sup.5, individually, are monocyclic alkyl having six or more carbon atoms, acyclic alkyl having nine or more carbon atoms, or alkaryl having nine or more carbon atoms; R.sup.6 is hydrocarbyl, preferably alkyl; n has a value from zero to about ten; (b) vinyl esters of alkanoic acids having at least eight carbon atoms; (c) substituted styrenes wherein the substituent group or groups have a total of three or more carbon atoms; and mixtures thereof; said polymer having surface energy properties such as to form a stable bond with said substrate. The polymer, used alone or in a blend, serves as a coating, a tiecoat, an adhesive or a binder.
