ADDUCTS MAGNESIUM DICHLORIDE - ALCOHOL AND CATALYTIC COMPONENTS OBTAINED THEREFROM Russian patent published in 2016 - IPC C01F5/00 C08F10/06 C08F4/634 C08F4/654 C08F4/631 C08F4/651 

FIELD: chemistry.

SUBSTANCE: adducts of the claimed invention, in particular, used as precursors in obtaining catalytic components for the polymerisation of olefins, which have the reduced size of particles and/or narrow distribution of particles by the size. The solid adducts contain: MgCl₂, ROH alcohol, in which R represents a C₁-C₁₀ hydrocarbon group, present in a molar ratio with MgCl₂ in the interval from 0.5 to 5, aliphatic carboxylic acid, which has from 8 to 22 carbon atoms, or its metal salt, present in the quantity of less than 15 wt % with respect to the total adduct weight. The method for obtaining the adducts includes: contact of MgCl₂, ROH alcohol and aliphatic carboxylic acid in the quantity of less than 15 wt % with respect to the total weight of MgCl₂ and ROH and the said acid or salt; heating the system at such temperature that a liquid phase is obtained , which contains MgCl₂, alcohol and the said acid or metal salt; emulsification of the said liquid phase in a liquid medium, which is non-mixable with it; fast cooling of thus obtained emulsion when it contacts with an inert cooling liquid with obtaining an emulsified phase in the form of spherical particles as a result of hardening. The invention also relates to catalytic components for the polymerisation of the olefins, which are obtained by the interaction of the adducts with the compound of the transition metal of one of groups IV-VI of the periodic system of elements, to the catalyst for the polymerisation of alpha-olefins and to a method for polymerisation.

EFFECT: narrow distribution of particles by the size of the said adducts and simple method of obtaining thereof.
