Patent ID: 7223822

Claim:
A continuous process to produce a branched olefin polymer comprising: 1) selecting a first catalyst component capable of producing a polymer having a weight of 100,000 or less and a crystallinity of 20% or less under selected polymerization conditions; 2) selecting a second catalyst component capable of producing polymer having a weight average molecular weight of 100,000 or less and a crystallinity of 20% or more at the selected polymerization conditions; 3) contacting a said first catalyst component or said second catalyst component, one or more activators, and one or more C2 to C40 olefins in a first reaction zone, at a temperature of greater than 70° C., and at a residence time of 120 minutes or less; and 4) transfering the contents of the first reaction zone directly to a second reaction zone and further contacting the contents with said first catalyst component, or said second catalyst component, one or more activator, and one or more C2 to C40 olefins, at a temperature of greater than 70° C., and at a residence time of 120 minutes or less; and 5) optionally, transferring the contents of the second reaction zone directly to a third reaction zone and further contacting the contents with said first catalyst component or said second catalyst component, one or more activators, and one or more C2 to C40 olefins, at a temperature of greater than 70° C., and at a residence time of 120 minutes or less; and 6) recovering a branched olefin polymer comprising at least 50 mole % of one or more C3 to C40 olefins, wherein: a) the first catalyst is present in at least one reaction zone selected from of the first and second reaction zones and second catalyst is present in at least one reaction zone; and (b) in at least one of the first and the second of the first and second reaction zones the C 2 to C 40 olefin is a C 3 to C 40 alpha-olefin.
