Components of catalysts for polymerizing olefins having the general formula: VCln(OR)m in which R=a hydrocarbon radical having 1-18 C; or Rp1Si(OH)3-p, in which R1=a hydrocarbon radical, 1</=p</=3; 1.5</=n</=3, m=3-n; with X-ray powder spectrum, in which maximum intensity diffraction lines, which in the spectrum of normal VCl3 appear at d=5.75 ANGSTROM , d=2.67 ANGSTROM and d=1.74 ANGSTROM , exhibit a broadening of the half peak breath of at least three times for the diffraction line at d=5.75 ANGSTROM and of at least four times for the diffraction lines appearing at d=2.67 ANGSTROM and d=1.74 ANGSTROM , or said diffraction lines disappear. |
