FREE RADICAL POLYMERIZATION OF CONJUGATED DIENE BY SUSPENSION OR VAPOR-PHASE METHOD AND NEW SUPPORT SYSTEM FOR STARTING COPOLYMERIZATION OF CONJUGATED MONOMER AND ANOTHER MONOMER

摘要

PROBLEM TO BE SOLVED: To provide a method for a free radical polymerization of a conjugated diene by suspension or vapor-phase method and to obtain a new support system for copolymerization of the conjugated diene and another monomer. ;SOLUTION: This generally applicable method for vapor-phase or suspension free radical polymerization of a monomer comprises using a polymerization starting support system containing (a) one or more components for starting a free radical polymerization, (b) a carrier to which a component for starting the polymerization is applied and (c) one or more modifiers influencing an occasional reaction rate and/or the properties of product.;COPYRIGHT: (C)1999,JPO
