Abstract
Disclosed is the homogenous reaction at 40-200° C. of MgX,−nR,OH (where n=2.0-6.4) with TiX,and a higher (C,-C,) alkyl ester of a carboxylic acid, optionally in the presence of a solvent. In such a completely homogenous reaction, no carrier appears. In order to obtain a product in the liquid stage, the molar ratio between the ester and the MgX,.nR,OH should be at least 0.8/j wherein j is the number of carboxyl groups in the ester. If the ester has two carboxyl groups, for instance, j is 2 and the molar ratio should be at least 0.8/2, that is, 0.4.
