Zusammenfassung:	FIELD: production of polyolefins having short branched side chains. SUBSTANCE: polymerization is carried out in the presence of catalyst of Ziegler-Natte type which comprises chromium and/or vanadium and/or titanium and cocatalyst. Catalyst of trimerization of alpha-olefins which is prepared by interaction of chromium salt with 2-4.13 moles of metal amide and with excess of ether is used as said cocatalyst. Thus linear polyolefins having high strength are prepared. EFFECT: improved efficiency of the method. 10 cl, 6 dwg , 17 tblu
