Abstract
The object of the present invention is a process of preparation of a graft copolymer obtained by pre-irradiation grafting of vinyl monomers onto polyolefins or fluorinated polyethylenes, in particular, of grafting acrylic or methacrylic acid onto polyethylene and/or polypropylene and subsequently loading a metal, such as a transition metal on the graft copolymer obtained. Such metal-loaded graft copolymers find use, especially as catalysts, e.g. for hydrogenation reactions.
