ABSTRACT

The adhesion between a polyolefin and other materials is poor, due to its chemical inertness, which prevents formation of chemical or hydrogen bonds. Several methods for modification of polyolefin surfaces have been developed in order to improve the adsorption of dyes and thus printability, increase the wetting with water, and enhance the adhesion to other materials. The most common way to overcome the problem mentioned above is surface modification by graft copolymerization of a

polar monomer [1-6]. Photografting, due to its low cost, is one of the more favored graft copolymerization methods, which can modify the surface of polymer materials without altering their bulk properties.
