FIELD: polymers. SUBSTANCE: invention relates to rheologically modified polyethylene containing less 0.5 wt.-% of gel, index of composition width distribution above 50% and molecular mass distribution value (Mw/Mn) less 4.0. The proposed polymer shows the improved rheological indices and/or indices of melt strength as compared with nonmodified polymer. Also, invention relates to a mixture of polymers containing rheologically modified polymers and to a method of synthesis of rheologically modified polymers. EFFECT: improved technological parameters of polyolefin. 31 cl, 16 tbl, 4 dwg
