ENHANCED SOLUBILITY OF MAGNESIUM HALIDES AND CATALYSTS AND POLYMERIZATION PROCESSES USING SAME

摘要

A METHOD FOR INCREASING THE SOLUBILITY OF A MAGNESIUM HALIDE INCLUDES PROVIDING AN ELECTRON DONATING SOLVENT, CONTACTING A MAGNESIUM HALIDE WITH THE SOLVENT; AND PROVIDING AN ELECTRON DONOR COMPOUND TO FORM A MAGNESIUM HALIDE COMPOSITION. THE COMPOSITION IS CHARACTERIZED BY A SOLUBILITY IN THE ELECTRON DONOR SOLVENT THAT DOES NOT DECREASE UP TO THE BOILING POINT OF THE SOLVENT.A POLYMERIZATION CATALYST PRECURSOR COMPOSITION COMPRISES THE PRODUCT OF MIXING THE MAGNESIUM HALIDE COMPOSITION WITH A TRANSITION METAL COMPOUND. ACTIVE CATALYSTS PREPARED FROMSUCH PRECURSORS AND A METHODS OF POLYMERIZATION USING SUCH CATALYSTS ALSO DISCLOSED.(FIG 1)
