PROCESS FOR THE PREPARATION OF COMPLEX COMPOUNDS OF TRANSITION METALS TO BE USED AS CATALYSTS FOR POLYMERISATION AND COPOLYMERISATION OF OLEFINS IN COMBINATION WITH ALUMINIUM-ORGANIC COMPOUNDS

摘要

A process for the preparation of complex compounds of transition metals to be used as catalysts for polymerization and copolymerization of olefins in combination with aluminium-organic compound having the general formula Al Rp Y3-p, where R is a lower alkyl or iso-alkyl, Y is chlorine or hydrogen, and p is from 1 to 3, consisting in the interaction between solutions of a metal compound MXa, where M is a transition metal belonging to Groups IVA-VA of the periodic system, X is a halogen or an oxy-halogen, n is the number characterizing the valency of M, and a solution of ligand D, selected from the group consisting of---(a) polyglycolic ethers of monoatomic alcohols R-(CH2 CH2O)2-OH, where R=C2H13-C5H19 and K iks from 3 to 9,(b) polyglycolic ethers of polyatomic alcohols (R-COOCH2)2 C[CH2(CH2CH2O)k-OH], where R=C4H9-C6H13 and K=2.5-29;(c) polyglycolic esters of carboxylic acids R-CO(CH2-CH2O)-----OH, where R=11H2a-C17H35 and K=10-160 and anhydrosorpitols of carboxylic acids as shown in Fig. 1.(Chemical Formula)where R=C11H23-C17-H35; k1+K2+K3=20-85, in aromatic or chlorine-containing solvents like benzene or carbon tetrachloride in an inert atmosphere with subsequent separation and drying of the precpitated complex compound.
