ABSTRACT:
A method for reducing sheeting during polymerization of an alpha-olefin by feeding either a positive charge generating (MgO, ZnO, Al.sub.2 O.sub.3, CuO, and mixtures thereof) or a negative charge generating (V.sub.2 O.sub.5, SiO.sub.2, TiO.sub.2, Fe.sub.2 O.sub.3, and mixtures thereof) inorganic chemical additive to the reactor responsive to particular static levels in the reactor. The chemical additive is added in amounts which substantially neutralizes the electrostatic charge in the reactor.
