<p>- i This invention is concerned with an article comprising a polyolefin substrate and adherent thereto a vinyl addition polymer of (1) monomers comprising at least 5% by weight a primary monomer selected from a) monomers having the formula wherein X is -O-, -NH- or -NR5-; R1 and R7, individually, are H, methyl or ethyl, R2 is H or an organic radical, preferably -COOH, -CONH2 or -COOR6; R3 is H or an organic radical, preferably methyl, other alkyl having up to about five carbon atoms, -CH2COOR6, -COOR6 or -CH2COOH; R4 and R5, individually, are mono cyclic alkyl having six or more carbon atoms, acyclic alkyl having nine or more carbon atoms, or alkaryl having nine or more carbon atoms; R6 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; -ii- c) substituted styrenes wherein the substituent group or groups have a total of three or ore carbon atoms; and mixtures thereof; and optionally (2) one or more substituted ethylene supplementary monomers; 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.</p> |
