Abstract
A process for producing sticky polymers at polymerization reaction temperatures in excess of the softening temperatures of the sticky polymers in a fluidized bed reactor in the presence of an inert particulate material which comprises utilizing as a support material for the catalyst, a support which includes silica having an average particle size of from about 60 to about 200 microns.
