Abstract
Abstract This invention is concerned with an article comprising an untreated 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 5 -; R 1 and R 7 , individually, are H, methyl or ethyl; R 2 is H or an organic radical, preferably -COOH, -CONH 2 or -COOR 6 ; R 3 is H or an organic radical, preferably methyl, other alkyl having up to about five carbon atoms, -CH 2 COOR 6 , -COOR 6 or -CH 2 COOH; R 4 and R 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 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) alkyl substituted styrenes wherein the substituent group or groups have a total 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 with other polymers, serves as a coating, a tiecoat, an adhesive or a binder.
