ABSTRACT:
A process for producing sticky polymers at polymerization reaction temperatures in excess of the softening temperature of the sticky polymers in a fluidized bed reactor catalyzed by a transition metal catalyst, which comprises conducting the polymerization reaction above the softening temperatures of the sticky polymers in the presence of about 0.3 to about 60 weight percent, based on the weight of the final product of an inlet particulate material having a mean particle size of from about 0.01 to about 10 micron meters whereby polymer agglomeration of the sticky polymers is maintained at a size suitable for continuously producing the sticky polymers.
