Abstract
Procedure for obtaining catalysts for polymerization, which consist of the product of the reaction between magnesium ethylate and a chlorinated titanium compound (component A), and an organometallic compound (component B), characterized in that component A is Forms by reacting 0.5 to 5 molar parts of magnesium ethylate, 1-1.9 molar parts of titanium tetraisopropylate and 2.1 - 3.0 molar parts of titanium tetrachloride in the presence of inert dispersants, at a temperature of 20 - 120ºC.
