A method for producing a layer of a metal, metal oxide or metal carbide on a polyolefin, by contacting a surface of said polyolefin with a thermally decomposable metal compound in the gas phase, while said polyolefin is heated at or above the decomposition temperature of the metal compound, in the presence of a gaseous carrier and/or reactant or reactant mixture, is disclosed..
