<p>Polyolefins, esp. polypropylene, have adherent vinyladdn. polymer of monomer comprising at least one monoer of formula (I) A is H or methy1, B is H or methy1 and R is CH2, CHCH3 ! or C(CH3)2; the polymer having a total surface energy 22-42 dynes per cm, the energy having a nonpolar dispersive component 20-38 dynes per cm and a polar component up to 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 the polymer.</p> |
