Abstract
A storage stable, improved catalyst is obtained when an aluminum-reduced titanium trichloride catalyst which has been modified by treatment with an electron donor is heated at a temperature and for a period of time sufficient to drive the reaction to completion. In some instances this will involve the removal of gas which has been generated during the modification. In the usual practice a temperature of about 90.degree. C. and a period of about 90 minutes will be employed.
