Precursor for polyolefin catalyst

A method for synthesis of a catalyst precursor with controlled morphology;

• said method comprising the following steps:
• reacting predetermined amount of magnesium metal particles with an alcohol at a temperature ranging between 35° C. to 50° C. under agitation to obtain a reaction mixture;
• adding a predetermined amount of titanium tetrachloride to the reaction mixture leading to the evolution of hydrogen from the reaction mixture;
• heating the reaction mixture gradually until the temperature of the mixture reaches to a reflux temperature and refluxing the reaction mixture until the time the evolution of hydrogen from the mixture stops completely;
• increasing the temperature of the reaction mixture to about 100° C. to remove the excess alcohol in the reaction mixture to obtain a precursor and subjecting the same to drying.
