FIELD: plastic processing.
SUBSTANCE: invention relates to a method for degassing elastomer-containing media, such as elastomer solutions and dispersions in particular, and degassing devices for carrying out said method. Method for removing volatile compounds from an elastomer-containing medium (EM) containing at least one elastomer and at least one volatile compound comprises feeding the elastomer-containing medium (EM) in a degassing device, which is operated so that volatile compounds are removed from the elastomer-containing medium (EM) through the vents of the degassing device and, thus, the content of volatile compounds in the elastomer-containing medium (EM) is reduced, and during the drainage from the degassing device, the polymer is recovered from the elastomer-containing medium as a product P, which then has a lower proportion of volatile compounds than the elastomer-containing medium (EM) supplied to the degassing device, and preferably has a total content of volatile compounds of 1 wt. % or less based on the mass of the elastomer.
EFFECT: invention provides effective removal of volatile compounds from elastomer-containing media.
