Abstract: A process for continuously polymerizing from the vapor state at least one polymerizable monomer or a mixture can be economically and efficiently converted to polymeric substance with a high yield catalyst in a vapor phase polymerization process using a stirred-bed, quench cooled, horizontal reactor together with essentially off-gas recycle and melt finishing. The method is further characterized by being essentially isobaric at least up to the polymer finishing steps.

Abstract: ETHYLENE, PROPYLENE AND MIXTURES THEREOF ARE POLYMERIZED WITH A CATALYST PREPARED BY DISTRIBUTING A MINOR AMOUNT OF TRANSITION METAL OXIDE OF GROUPS VA AND VIA OF THE PERIODIC TABLE UPON A MAJOR AMOUNT OF ALUMINA HAVING A SURFACE AREA WITHIN THE RANGE OF 150 TO 500 M.2/GM. AND A PORE DIAMETER WITHIN THE RANGE OF 100 TO 200 A., THEN REDUCING THE TRANSITION METAL TO AN AVERAGE VALENCE ABOUT 1 LESS THAN MAXIMUM AND CHLORIDING THE RESULTING COMBINATION WITH ANHYDROUS HYDROGEN CHLORIDE TO A CHORINE CONTENT OF ABOUT 2 TO 5 PERCENT BY WEIGHT.
