摘要：
The invention relates to a process for preparing a foamed polymer composition using expandable hollow microbeads, wherein, in a first process strand, first starting materials, which include at least the predominant portion of the polymer or polymers to be used, are mixed and degassed to give a premix, whereafter this premix is subjected to a pressure such that the pairing of this pressure with the temperature of the premix is below the pressure and temperature pairing that is critical for triggering the expansion of the hollow microbeads to be used, wherein, in a second process strand, second starting materials, including the hollow microbeads to be used, are degassed, whereafter the second starting materials treated in the second process strand are added to the premix prepared in the first process strand, whereafter the second starting materials are mixed with the premix.
