Abstract
Abstract Polyolefins, particularly polypropylene, have adherent thereto vinyl addition polymer of monomer comprising at least one monomer of the formula: wherein A is H or methyl, B is H or methyl and R is CH 2 , CHCH 3 or C(CH 3 ) 2 ; the polymer having a total surface energy between about 22 and about 42 dynes per cm, said energy having a non- polar dispersive component between about 20 and about 38 dynes per cm and a polar component up to about 15 dynes per cm, the polar component being not more than 38% of the total surface energy. The polyolefin may be untreated to enhance bonding of polymer thereto. The adherent polymer may be used alone or in admixture with other polymer and may serve as a coating, tie coat, adhesive or binder. Polyolefins bearing the polymer may be in the form of nonwoven fabrics, laminates or flocked fabrics.
