<p>Primer compositions are disclosed which are a homogeneous, fluid, uncured suspension of discrete particles of a polar group-containing modified propylene polymer in a film forming resin material, the particles having an average particle size of less than 5 mu m, and the primer composition being substantially free of solvent for the polar group-containing modified propylene polymer. The compositions are useful in bonding layers of polypropylene or the like to a variety of substrates.</p> |
