FIELD: chemistry of polymers.
SUBSTANCE: invention relates to radiation modification of polymers, in particular, to a method of radiation cross-linking articles made of polyolefins. Method involves irradiation of articles in unsaturated hydrocarbon medium comprising the length chain C2-C12. Method enhances the effectiveness of cross-linking polyolefins at relatively low absorbed doses of ionizing radiation. Invention can be used in manufacture of heat-stable petroleum-plunged cables, pipelines, thermally shrinking films and tubes.
EFFECT: improved method for radiation cross-linking.
