1. An article comprising an untreated 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 ##STR6## wherein X is --O--, --NH-- or --NR5 --;

  • R1 and R7, individually, are H, methyl or ethyl;

    R2 is H, --COOH, --CONH2, or --COOR6,R3 is H, alkyl having up to 5 carbon atoms, --CH2 COOR6, --COOR6 or --CH2 COOH;

    R4 and R5, individually, are monocyclic alkyl having 6 to 20 carbon atoms, acyclic alkyl having 9 to 20 carbon atoms, or alkaryl having 9 to 18 carbon atoms;

    R6 is hydrocarbyl; and

    n having a value from zero to about ten;

    (b) vinyl esters of alkanoic acids having 8 to 20 carbon atoms;

    (c) Alkyl substituted styrene wherein the substituent group or groups have a total of 3 to 15 carbon atoms;

    and mixtures thereof and optionally (2) or more substituted ethylene supplementary monomers;

    said polymer having surface energy properties such as to form a stable bond, having a 180°

    peel strength greater than 2 pounds per inch, with said substrate.
