Abstract

A device for preparing a liquid polymer blend is proposed having a storage container for the liquid polymer blend; a degassing device, which is arranged downstream of the storage container, for the liquid polymer; a gassing device, which is arranged downstream of the degassing device, for adding an additive gas to the liquid polymer blend; a homogenization unit, which is arranged downstream of the gassing device, for the polymer blend to which the additive gas was added; and an output line, which is connected to the homogenization unit, for the homogenized polymer blend.
