Abstract

The invention can be used in the electro-technical industry, for production of inner cables. This resolves the reduction of migration of antioxidant from polyethylene granules, which results in an increased of the thermo-oxidative stability of the polyethylene and prolonging of the service life of cables with polyethylene insulation. The essence of the invention is that multicore phenolic antioxidant is bound in the presence of a peroxide initiator to low-density polyethylene, whose melted flow index in between 1.7 g/10 min to 2.5 g/10 min and the interval of polydispersion is 5.5 to 9.5.
