ABSTRACT:
Described herein is a continuous process for polymerizing 1-alkenes. In this process, which operates free of any hydrogen control feed, the resultant polymer has an inherent viscosity that is closely centered around a predetermined targeted value. If desired, the targeted value can be changed while the process is being performed. The process is carried out in a reactor that allows for essentially plug flow of material passing therethrough. Additionally, the temperature profile of the reactor is controllable.
