MAGNESIUM DICHLORIDE-CONTAINING ADDUCTS AND CATALYTIC COMPONENTS OBTAINED WITH THEM Russian patent published in 2009 - IPC B01J37/02 C08F4/654 C08F4/651 C08F4/64 C08F4/655 C08F10/00 

FIELD: chemistry.

SUBSTANCE: described are solid Lewis adducts, containing MgCl₂, Lewis base (LB), belonging to simple ethers, complex alkyl esters of C₁-C₁₀ aliphatic carboxylic acids, ketones, silanes or amines, and alcohol ROH, where R represents C₁-C₁₅ carbon group, optionally substituted with heteroatom-containing groups, said compounds being in molar ratio with each other, which is determined by the following formula MgCl₂(ROH)_m(LB)_n(H₂O)_p, in which m lies in interval from 0.05 to 6, n lies in interval from 0.08 to 6 and p lies in interval from 0.01 to 0.6. Also described is method of obtaining said solid Lewis adduct, including (i) contacting of MgCl₂, alcohol ROH and Lewis base LB optionally in presence of inert liquid thinner; (ii) heating of system to temperature of mixture melting and sustaining said conditions in order to obtain fully melted adduct; and (iii) quick cooling of melted adduct and obtaining as a result its hardening; also described are catalytic components obtained during contacting of described above adducts with compounds of titanium of formula Ti(OR)_nX_y-n, where n equals from 0 to y, y represents titanium valency, X represents halogen and R represents alkyl radical, which has 1-10 carbon atoms, or COR group, and containing electron donor, selected from complex esters, simple ethers, amines and ketones; described is catalytic system for alpha-olefin polymerisation and method of olefin polymerisation.

EFFECT: good morphological stability of catalyst and high polymerisation activity.
