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.
