Abstract
The productivity of a catalyst in a gas phase polymerization of olefins (e.g. grams of polymer per gram of catalyst) may be increased by including in the gas phase from 1 to 20 weight % of an inert non-polymerizable hydrocarbon. The hydrocarbon may be in gaseous form but preferably is in liquid form.
