Catalyst residue removal

Claim 1

A METHOD OF REMOVING CATALYST RESIDUES FROM A POLYMER PREPARED BY CATALYTIC POLYMERIZATION IN THE PRESENCE OF A CATALYST WHICH FORMS ON COMMINGLING AT LEAST TWO ESSENTIAL COMPOUNDS, ONE OF SAID COMPONENTS BEING A METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF GROUPS, IV, V, VI AND VIII METAL COMPOUNDS AND ANOTHER OF SAID COMPONENTS BEING SELECTED FROM THE GROUP CONSISTING OF ORGANOMETALS, METAL HYDRIDES AND METALS OF GROUPS I, II AND III, WHICH CONSISTS OF CONTACTING SAID POLYMER PRESENT IN SOLUTION WITH A TREATING AGENT COMPRISING AN ALKYLENE OXIDE HAVING FROM 2 TO 8 CARBON ATOMS AT A TEMPERATURE SUCH THAT THE POLYMR WILL NOT BE DEGRADED FOR A TIME RANGING FROM 5 TO 120 MINUTES, PASSING THE RESULTING TREATED POLYMER SOLUTION OVER A BED OF AN ACTIVATED SORBENT, AND RECOVERING THE THUS TREATED POLYMER FROM THE SOLUTION THEREOF SUBSTANTIALLY FREE OF CATALYST RESIDUES.

Claim 2
