ADDITION COMPOUND OF CARBOXYLIC ACID WITH HALIDE OR HALOGENOCARBOXYLATE OF RARE EARTH ELEMENT OR GALLIUM, ANHYDROUS ADDITION COMPOUND OF HALIDE OF RARE EARTH ELEMENT OR GALIUM WITH NTIROGEN OR OXYGEN DONOR, AND PRODUCTION METHOD AND CATALYTIC USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an addition compound of a carboxylic acid with a halide or halogenocarboxylate of a rare earth element or gallium, for use in production of a polymerization catalyst. SOLUTION: The addition compound of a carboxylic acid with a halide or halogenocarboxylate of a rare earth element or gallium is provided for solving the problems on the matter. The compound is obtained by reacting HX (X is a halogen) with a carboxylate of a rare earth element or gallium in a solvent selected from among an alkane, a cycloalkane, an aromatic solvent and their mixture.
