| titleOfInvention | Process for producing a semi-continuously operated copolymer |
| abstract | The present invention relates to a process for the production of a copolymer in a semi-continuous operation in a polymerization apparatus comprising a polymerization reactor connected to a metering apparatus, wherein the acid monomer is fed into the metering apparatus as well as the polyether macro. Monomer and water are charged into the polymerization reactor each time, acid monomer is metered into the polymerization reactor from the metering device via the acid monomer metering line, and before the acid monomer is metered into the polymerization reactor and During the metering, an aqueous medium in which a radical polymerization initiator is introduced into the polymerization reactor so that the acid monomer and the polyether macromonomer are reacted by radical polymerization in the formation of the copolymer in the polymerization reactor During the radical polymerization, an aqueous medium containing a partial amount of copolymer is led from the polymerization reactor through the reaction mixture line. The reaction mixture line is connected to the acid monomer metering line via a mixing device, and the aqueous medium containing the derived copolymer is mixed with the acid monomer in the mixing device during the acid monomer metering. And after mixing, it is returned to the polymerization reactor via an acid monomer metering line. |
