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. ^ 22 cl, 3 tbl, 20 ex |
