Abstract
A method and a device for admixing additives into a polymer melt made of non-extracted polyamide 6 are disclosed. The polymer melt is combined in a highly concentrated form with an additional melt flow without additives and mixed therewith. Additionally, a part of the melt is branched off from a main melt flow (), wherein the sub-melt flow () is transported into a dispersing device () and is supplied and mixed with one or more additives (). The side-melt flow () with additives is then returned into the main melt flow (), mixed with the main melt flow, and subsequently supplied for further processing.
