<p>Untreated polyolefins, particularly polypropylene, have adherent thereto vinyl addition polymer of monomer comprising at least 5% by weight of one or more of the following primary monomers:… (a) at least one monomer having the formula …<CHEM>… wherein X is -O-, -NH- or -NR<6>-;… R<1> and R<2> are the same or different and are H, methyl or ethyl;… R<3> and R<4> are the same or different and are H or an organic radical;… R<5> and R<6> are the same or different and 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;… n is a number having a value from zero to about ten;… (b) at least one vinyl ester of at least one alkanoic acid having at least eight carbon atoms;… (c) at least one substituted styrene wherein the substituent group or groups have a total of three or more carbon atoms;… said polymer having surface energy properties such as to form a stable bond with said substrate. …<??>The adherent polymer may be used alone or in admixture with other polymer and may serve as a coating, tiecoat, adhesive or binder. Polyolefins bearing the adherent polymer may be in the form of nonwoven fabrics, laminates or flocked fabrics.</p> |
