MAGNESIUM DICHLORIDE - ALCOHOL ADDUCTS AND CATALYST COMPONENTS BASED ON THEM Russian patent published in 2008 - IPC C08F4/02 C08F10/02 C08F10/06 C08F4/64 C08F4/654 

FIELD: chemistry.

SUBSTANCE: invention concerns an adduct of the formula MgCl₂·(EtOH)_m(ROH)_n(H₂O)_P,_{where R is a hydrocarbon group C1-C15 different from ethyl, n and m indices are more than 0, complying with the equation (n+m) ≥ 0.7 and 0.05 ≤ n/(n+m) ≤ 0.95, and p is 0-0.7 if R is methyl and (n+m) is 0.7-1, n/(n+m) is 0.05-0.45.}

EFFECT: catalyst components based on the claimed adducts can comprise olephine polymerisation catalysts characterised by improved activity in comparison to the catalysts based on the adducts obtained by earlier technologies.
