| titleOfInvention | Semi-continuous procedure for the preparation of copolymers |
| abstract | Procedure for the preparation of a copolymer in semi-continuous mode of operation in a polymerization device containing a polymerization reactor attached to a dosing equipment, where an acid monomer is respectively charged to the dosing equipment and a polyether macromonomer and water are charged to the polymerization reactor; the acidic monomer is metered from the metering equipment through an acidic monomer metering line into the polymerization reactor, before and / or during the metering of the acidic monomer into the polymerization reactor a free radical polymerization initiator is introduced into the polymerization reactor so that an aqueous medium originates in the polymerization reactor, in which the acid monomer and the polyether macromonomer react with the formation of the copolymer by free radical polymerization; the molar ratio between the total of the acidic monomer used and the total of the polyether macromonomer used is from 20: 1 to 1: 1; such that the molar ratio between the acid monomer initially charged in the polymerization reactor and the acid monomer dosed in the polymerization reactor is from 3: 1 to 1:10, where during free radical polymerization of the polymerization reactor it is Continuously discharges a partial amount of the aqueous medium containing the copolymer through a reaction mixing line, which is connected to the acid monomer dosing line by means of mixing equipment, the aqueous medium containing the copolymer discharged into the Mixing equipment during the dosing of the acidic monomer is mixed with the acidic monomer and after mixing it is reintroduced into the polymerization reactor through the acidic monomer metering line. |
