VERFAHREN ZUR KONTINUIERLICHEN HERSTELLUNG VON POLYCARBONATEN NACH DEM SCHMELZUMESTERUNGSVERFAHREN |
| 摘要 |
<p>Preparation of polycarbonates from oligocarbonates in the melt, by ester exchange of diaryl carbonates with diphenols in the presence of a catalyst. The polycondensation is conducted at high specific surface and a permanent free film formation rate under gravity, using a reactor provided with a rotating circular perforated disk.</p> |
