METHOD FOR THE PRODUCTION OF HIGH-PURITY POLYMER GRANULES |
| 摘要 |
A process for producing polymer pellets is disclosed. The process that is particular suitable for making polycarbonate pellets entails extruding a polymer melt, cooling the extrudate by contacting it with a cooling fluid and pelletizing the solidified polymer. The process is characterized in that the cooling fluid has a solids particle content of at most 10 ppm. |
