<p>Cleaning a thermoplastic polymer (4) comprising at least one dispersed filler, comprises (a) preparing a polymer melt (6) of the thermoplastic polymer, and (b) filtering the polymer melt, where the dispersed filler prior to the step (b) is at least partially converted into a coagulated and a filterable form. An independent claim is also included for a device (1) for cleaning the thermoplastic polymer comprising a means for producing a polymer melt from the thermoplastic polymer, a filter means (10), and a means for producing sound waves (14), preferably ultrasonic waves.</p> |
