CONTROLLING MOISTURE IN AND PLASTICIZATION OF BIORESORBABLE POLYMER FOR MELT PROCESSING |
| 摘要 |
Methods and systems for controlling the moisture content of biodegradable and bioresorbable polymer resin during extrusion above a lower limit that allows for plasticization of the polymer resin melt and below an upper limit to reduce or prevent molecular weight loss are disclosed. Methods are further disclosed involving plasticization of a polymer resin for feeding into an extruder with carbon dioxide and freon. |
