A POLYMERIZATION PROCESS INCLUDES CONTACTING THE FOLLOWING IN A GAS-PHASE REACTOR SYSTEM UNDER POLYMERIZATION CONDITIONS FOR MAKING A POLYMER PRODUCT: A METALLOCENE-BASED CATALYST SYSTEM INCLUDING A SUPPORTED CONSTRAINED GEOMETRY CATALYST, AT LEAST ONE MONOMER, AND AN ADDITIVE SELECTED FROM A GROUP CONSISTING OF AN ALUMINUM DISTEARATE, AN ETHOXYLATED AMINE, AND A MIXTURE THEREOF. THE ADDITIVE MAY BE SELECTED FROM A GROUP CONSISTING OF AN ALUMINUM DISTEARATE, AN ETHOXYLATED AMINE, POLYETHYLENIMINES, AND OTHER ADDITIVES SUITABLE FOR USE IN THE PRODUCTION OF POLYMERS FOR FOOD CONTACT APPLICATIONS AND END PRODUCTS, INCLUDING A MIXTURE OF A POLYSULFONE COPOLYMER, A POLYMERIC POLYAMINE, AND OIL-SOLUBLE SULFONIC ACID, IN A CARRIER FLUID, AND MIXTURES THEREOF. |
