A process for introducing steam into polymer dispersions or polymer solutions by introducing steam into the lower part of reaction apparatuses and deodorization apparatuses, in particular deodorization columns, which comprises introducing the steam beneath the liquid surface of the dispersion or the polymer solution.

Introducing steam into polymer dispersions

The process of the present invention for removing residual volatiles from polymer dispersions by performing first chemical deodorization using an initiator to remove residual monomers and then physical deodorization to remove volatile constituents comprises conducting the chemical deodorization for as long as the decrease in monomers is greater than the increase in secondary components introduced into the dispersion by the initiator, to result reliably in polymer dispersions having a residual volatiles content of less than or equal to 100 ppm.

Process for cooling dispersions and liquids

A process for cooling a continuously inflowing liquid, in particular a dispersion, in vacuo which comprises subjecting the liquid to a flash evaporation in a separator.
