Abstract
A process for compounding polymer dispersions, which comprises circulating the polymer dispersion from a vessel (7) having a stirring device (6) through a line (3) having a mixing device (2) by means of a pump (4) which is located in the line (3), and, before the entry of the circulated polymer dispersion into the mixing device (2), metering at least one solution or dispersion of at least one compounding material from at least one stock container (5) via a supply line (9) into the circulated polymer dispersion.
Claims8
A process for the compounding of an aqueous polymer dispersion, which comprises
- a) circulating the aqueous polymer dispersion between a vessel (7) having a stirring device (6) and a line (3) having a mixing device (2) by means of a pump (4) which is located in the line (3), and
- b) metering into said circulated polymer dispersion at least one solution or dispersion of at least one compounding material before the entry of the circulated polymer dispersion into the mixing device (2),
- and wherein the solution or dispersion of the compounding material is supplied from at least one stock container (5) via a supply line (9).
