ABSTRACT:
Metal carboxylates which may be used for the polymerization of monomers suitable for Ziegler-Natta polymerization are prepared by reaction of the organic C.sub.2-20 carboxylic acids on which the carboxylates are based with ammonia and/or amines and/or tetraalkyl ammonium hydroxides and the corresponding metal nitrates in the presence of inert organic solvents at temperatures of 0.degree. to 150.degree. C.
