FIELD: preparation of various molded products. SUBSTANCE: possibility of extrusion at lower pressure in extrusion die and lower electric current consumption is attained due to the fact that ethylene polymer has new properties: polydispersity index is at least about 3.0; flow behavior (FBI) index and relaxation spectrum index (RSI) is such that (RSI) (FBI0,7) (FBI) is about 26; index of distribution of crystallizing chains along Lw/Ln is about 0.3. Ethylene polymer has about 0.3 long-chain branching per 1000 carbon atoms of main chain and is prepared by polymerization of ethylene and optionally higher alpha-olefin with catalyst composition composed of metallocene catalyst and cocatalyst. EFFECT: improved properties of molded products. 13 cl, 2 dwg, 2 tbl
