FIELD: production of polyethylene. SUBSTANCE: hydrosilica gel is mixed with silica powder at their ratio (0.01-0.21):1 respectively. Said hydrosilica gel is prepared by neutralization of sodium silicate solution with solution of mineral acid, content of sodium oxide in it being 0.2-1 mass % as calculated for silicium dioxide. EFFECT: increases specific surface and volume of pores in desired product, simplifies the process. 1 tbl
