Abstract
The present disclosure relates to a process and/or method for producing a polymer dispersion by free-radically initiated emulsion polymerization of radically polymerizable ethylenically unsaturated monomers within a polymerization reactor. The polymer dispersion obtained is transferred to a post-treatment reactor and is post-treated therein. The polymer dispersion within the post-treatment reactor is conveyed, simultaneously to the post-treatment, to a circuit for filtration and analysis and is then subsequently fed back into the post-treatment reactor.
Claims12
A method for preparing a polymer dispersion, the method comprising the steps of:
- providing a polymerization reactor;
- obtaining a polymer dispersion by free-radically initiated emulsion polymerization of radically polymerizable ethylenically unsaturated monomers within the polymerization reactor;
- transferring the polymer dispersion obtained to a post-treatment reactor;
- and
- post-treating the polymer dispersion within the post-treatment reactor by physical and/or chemical methods and wherein the polymer dispersion in the post-treatment reactor is conveyed simultaneously to the post-treatment and to a circuit for filtration and analysis and then is subsequently fed back into the post-treatment reactor.
