IN A PROCESS FOR THE POLYMERIZATION OF ALPHA-OLEFINS WHICH COMPRISES CONTACTING AN ALPHA-OLEFIN FREE FROM BRANCHING AT THE 2-POSITION WITH A CATALYTIC COMPOSITION CONSISTING ESSENTIALLY OF AN ALUMINUM SESQUIHALIDE HAVING THE FORMULA ALR1.5X1.5 WHEREIN R IS A HYDROCARBON RADICAL HAVING FROM 2 TO 12 CARBON ATOMS AND X IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE AND BROMINE, AN ESSENTIALL AMORPHOUS TITANIUM TRICHLORIDE AND METHYL TETRAHYDROFURAN SUSPENDED IN AN INERT HYDROCARBON SOLVENT; WHEREIN THE MOL RATIO OF ALUMINUM SESQUIHALIDE TO METAL HALIDE IS FROM 1:15 TO 10:1 AND THE MOL RATIO OF ALUMINUM SESQUIHALIDE TO METHYL TETRAHYDROFURAN IS FROM 10:1 TO 5:4, THE IMPROVEMENT WHICH CONSISTS IN CONDUCTING THE POLYMERIZATION IN THE PRESENCE OF FROM 5 PARTS TO 250 PARTS PER MILLION BY WEIGHT, BASED ON THE WEIGHT OF THE SOLVENT, OF HYDROGEN.
