Abstract
A method for reducing sheeting during polymerization of alpha-olefins in a fluidized bed employing catalysts prone to cause sheeting which comprises feeding a material carrying a static electric charge opposite to the static charge in said bed, said opposite charge of said material being generated by passing said material in contact with a surface adapted to impart said static electric charge to said material opposite the charge existing in said bed.
