Abstract
A process for polymerizing olefins using a fluidized bed, in which the monomer entry point is located at a point above the bed height. A pre-polymerization step can be conducted using a Z/N catalyst along with an alkane diluent, and resultant liquid phase is introduced into the fluidized bed above the bed height. The process may use several reactors in series arrangement.
