| 摘要 |
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 <IMAGE> 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 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.
