Abstract
Polymerization of a monomer, either alone or present in major proportion with one or more comonomers present in minor proportion, is accomplished by controlling the major monomer feed rate in response to a signal representative of the production rate of the polymerization process, unless the major monomer concentration within the reaction zone exceeds a preselected high limit causing the major monomer feed rate to be controlled in response to the concentration of the major monomer within the reaction zone. The flow of recycle diluent to the reaction zone is controlled in response to the concentration of major monomer within the reaction zone unless the solids concentration within the reaction zone exceeds a preselected high limit, in which case the flow of recycle diluent to the reaction zone is controlled in response to the concentration of solids within the reaction zone. Under ordinary operating conditions, when the preselected maximums have not been exceeded, the flow of major monomer to the reaction zone is controlled in response to the polymer production rate and the flow of recycle diluent to the reaction zone is controlled in response to the concentration of major monomer within the reaction zone.
