| titleOfInvention | Process for preparing polycarbonate and apparatus forpreparing polycarbonate |
| abstract | The present invention relates to aromatic dihydroxy compounds, carbonic acid diesters, and optionally to melting the catalyst in a prepolymerization vessel (4a / 4b). Combining to form a polycarbonate product; To transfer the polycarbonate product from the prepolymerization vessel (4a / 4b) step; The polycarbonate product was subjected to end-capping agent at a pressure of about 760 mmHg or more under a hermetic seal. Mixing; And transferring the polycarbonate product and the end-capping agent mixture to a subsequent polymerization vessel (9) The present invention relates to a process for preparing end-capped polycarbonate, which comprises the step of capping a product. A prepolymerization vessel 4a / 4b having an inlet and an outlet; A subsequent polymerization vessel 9 having an inlet and an outlet; Outlet of the prepolymerization vessel 4a / 4b And a mixer in fluid communication with the inlet of the subsequent polymerization vessel (9). And a charging section in which an end-capping agent is charged to the mixer, wherein the horn To a device for producing end-capped polycarbonate, wherein the aeration comprises a filling that is hermetically sealed at a pressure of at least 760 mmHg.
