Abstract
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 --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, --CH2 COOR6, --COOR6 or --CH2 COOH;
R4 and R5, 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;
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;
(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.
