ABSTRACT:
Polymeric articles made of, for example, polyethylene and copolymers of ethylene, are made more adherent to paint or dyes by first nitrating the polymer, then shaping or forming it in a mould having a polar surface and finally, cooling it in contact with that surface, or extruding a nitrated polymer onto a polar surface and allowing to cool in contact with that surface.
