METHOD OF INCORPORATING AT LEAST ONE SOLIDS POWDER A INTO A MELT CONTAINING AT LEAST A THERMOPLASTIC POLYMER B

摘要

The invention relates to a continuous method of incorporating at least one solids powder A into a melt containing at least a thermoplastic polymer B, in an extruder. The polymer B is fed into the extruder at one end either in the form of granules which are then melted in the extruder or in the form of a melt, and the solids powder A is fed into the extruder at the same point and/or downstream of the point at which the polymer B is fed into the extruder. Downstream of the feed-in point(s) of A and B water is injected into the extruder.
