CONTINUOUSLY OPERATED METHOD FOR PRODUCING COPOLYMERS

摘要

The invention relates to a method for producing a copolymer in continuous operation in a polymerization device, containing a polymerization reactor, which comprises supply lines and a drain, wherein radical polymerization initiators and acid monomers and polyether macro-monomers are introduced as monomer starting materials into said polymerization reactor through said supply lines, initiator, which is temperature-controlled to -20 to +120°C, monomer starting materials, and reaction composition, which contains copolymer, are provided in said polymerization reactor, and reaction composition, which contains copolymer, is conducted out of said polymerization reactor through said drain, wherein the introduction of said polyether macro-monomer into said polymerization reactor occurs separately from that of said acid monomer such that the polyether macro-monomer is mixed in the polymerization reactor with said initiator, monomer starting materials, and reaction composition containing copolymer and comes into contact with the acid monomer for the first time at the same time.
