A PROCESS FOR THE ACTIVATION OF TITANIUM TRICHLORIDE WHICH HAS BEEN PRODUCED BY THE REDUCTION OF TITANIUM TETRACHLORIDE WHICH IS CONTAMINATED WITH TITANIUM TETRACHLORIDE, AND WHICH HAS THEREAFTER BEEN WASHED WITH AN INERT HYDROCARBON, SAID TITANIUM TRICHLORIDE TO BE USED FOR THE POLYMERIZATION OF OLEFINS, WHICH PROCESS COMPRISES: HEATING SAID TITANIUM TRICHLORIDE WITH AGITATION AT A TEMPERATURE NOT EXCEEDING 100*C. IN THE ABSENCE OF OLEFIN BUT IN THE PRESENCE OF AN ORGANOMETALLIC POLYMERIZATION CATALYST-INERT HYDROCARBON MIXTURE, THE AMOUNT OF SAID ORGANOMETALLIC POLYMERIZATION CATALYST IN SAID VESSEL BEING FROM ABOUT 10 TO ABOUT 200 MOL PERCENT BASED ON THE AMOUNT OF TITANIUM TRICHLORIDE THAT IS PRESENT IN THE VESSEL, SEPARATING OFF SAID ORGANOMETALLIC POLYMERIZATION CATALYST-INERT HYDROCARBON MIXTURE, AND THEREAFTER WASHING THE TITANIUM TRICHLORIDE ONCE AGAIN WITH AN INERT HYDROCARBON, WHEREBY AN ACTIVATED AND SUBSTANTIALLY MOISTURE AND TITANIUM TETRACHLORIDE FREE CATALYST IS OBTAINED.
