Claim 1
Independent Claim
116 words
IN A PROCESS FOR POLYMERIZING ALIPHATIC 1-OLEFINS CONTAINING 2 TO 8 CARBON ATOMS WHEREIN THE 1-OLEFIN IS CONTACTED IN A REACTION ZONE WITH A CATALYST WHICH FORMS ON MIXING (1) AN ALKYLALUMINUM COMPOUND CONTAINING UP TO 15 CARBON ATOMS IN EAHC ALKYL GROUP AND UP TO 40 CARBON ATOMS PER MOLECULE AND SELECTED FROM THE GROUP CONSISTING OF TRIALKYLALUMINUM COMPOUNDS AND ALKYLALUMINUM HALODES, AND (2) A TITANIUM HALIDE, AT A TEMPERATURE IN THE RANGE OF 100 TO 500*F. AND A PRESSURE SUFFICIENT TO MAINTAIN THE REACTION MIXTURE IN THE LIQUID PHASE, THE IMPROVEMENT WHICH COMPRISES ADDING TO SAID REACTION ZONE 0.01 TO 10 MOLS OF ALLYL HALIDE PER MOL OF SAID ALKYLALUMINUM COMPOUND AND TITANIUM HALIDE.
