Claim 1
Independent Claim
85 words
A METHOD FOR POLYMERIZING AN ALIPHATIC 1-OLEFIN HAVING UP TO AND INCLUDING 8 CARBON ATOMS PER MOLECULE WHICH COMPRISES CONTACTING SAID OLEFIN WITH A CATALYST COMPRISING (A) A TITANIUM DERIVATIVE SELECTED FROM THE GROUP CONSISTING OF (1) COMPOUNDS CORRESPONDING TO THE FORMULA TI(OR)M, WHEREIN R IS AN ALKYL RADICAL CONTAINING FROM 1 TO 20 CARBON ATOMS AND THE COMPOUND CONTAINS UP TO A TOTAL OF 50 CARBON ATOMS AND WHEREIN M IS EQUAL TO THE VALENCE OF THE TITANIUM, (2) COMPOUNDS CORRESPONDING TO THE FORMULA
