ABSTRACT:
A method of producing a membrane of graft copolymer by irradiating a polyolefine film with ionizing radiation before or simultaneously with graft copolymerizing an olefinic monomer or a mixture of an olefinic monomer and a polyene compound onto the polyolefine is disclosed. The method is characterized by graft copolymerization wherein the polyolefine base film is reciprocated between a pair of fixed reversing rollers through a mobile roller.
