Abstract: 1. A PROCESS FOR THE MANUFACTURE OF A PARTICULATE CATALYST COMPOSITION (K) HAVING A PARTICLE DIAMETER OF FROM 0.1 TO 5 MM AND SUITABLE FOR THE POLYMERIZATION OF OLEFINS, COMPRISING A ZIEGLER CATALYST SYSTEM (Z) EMBEDDED IN A WAX, THE ZIEGLER CATALYST SYSTEM CONSISTING OF: (1) A GRAMS OF A PARTICULATE INORGANIC CARRIER HAVING A PARTICLE DIAMETER OF FROM 0.001 TO 2 MM. AND CONTAINING CHEMICALLY COMBINED METALS, AND (2) FROM 0.001A TO 0.1A GRAMS IN TERMS OF THE TRANSITION METAL IN CATALYST COMPONENT (2.1), OF A ZIEGLER CATALYST APPLIED TO SAID CARRIER, WHICH ZIEGLER CATALYST CONSISTS: (2.1) B GRAM-MOLES OF A CATALYST COMPONENT CONSISTING OF A CHLORIDE, OXYCHLORIDE OR ALKOXYCHLORIDE OF TITANIUM, ZIRCONIUM OR VANADIUM, AND (2.2) FROM 0.01B TO 100B GRAM-MOLES OF A CATALYST COMPONENT CONSISTING OF A SATURATED METAL ALKYL, SATURATED METAL ALKOXYALKYL OR SATURATED METAL ALKYLHALIDE OF ALUMINUM, MAGNESIUM OR ZINC OR A LITHIUM ALKYL, WHEREIN AN INTIMATE MIXTURE (G) HAVING A TEMPERATURE OF FROM 40* TO 120*C. AND CONSISTING OF C GRAMS OF THE ZIEGLER CATALYST SYSTEM (Z) AND 1C TO 100C GRAMS OF A MELT WAX HAVING A MELTING POINT ABOVE 30*C IS CONVERTED TO THE PARTICULATE CATALYST COMPOSITION (K) BY COMMUNITION OF SAID MIXTURE (G), IN WHICH 1 PART BY WEIGHT OF SAID INTIMATE MIXTURE (G) HAVING A TEMPERATURE OF FROM 40*C. TO 120*C. IS PASSED AT A RATE OF FROM 0.0001 TO 0.01 PART BY WEIGHT PER SECOND, INTO FROM 0.2 TO 25 PARTS BY VOLUME, SAID PARTS BY WEIGHT RELATING TO SAID PARTS BY VOLUME, SAID PARTS BY WEIGHT RELATING LIQUEFIED INERT GAS HAVING A TEMPERATURE OF FROM -30* TO -200:C AND IN MOTION AT A REYNOLDS NUMBER OF FROM 3.4X10**3 TO 5X10**4 WHEREUPON THE RESULTING PARTICULATE CATALYST COMPOSITION (K) IS SEPARATED FROM THE INERT GAS.
