Abstract
The present invention relates to a gas phase process for the polymerization of olefins utilizing a metallocene catalyst system to produce polymers having a low density and a relatively high molecular weight. More particularly, the gas phase process of the invention is directed forward the production of very low density polymers, for example rubbers, elastomers and plastomers.
