| titleOfInvention | PROCEDURE FOR OBTAINING NON-AROMATIC POLYESTERCARBONATES |
| abstract | PROCEDURE FOR THE PREPARATION OF NON-AROMATIC POLYESTERCARBONATES WITH A LIMIT VISCOSITY BETWEEN 0.9 AND 2.5 DL / G. IT INCLUDES THE FOLLOWING OPERATIONS: FIRST, A MIXTURE MADE UP OF 30 TO 100 BY WEIGHT OF POLYESTERDIOL IS PREPARED 70 TO A 0 BY WEIGHT OF POLYETHERDIOL, FOR 0.95 TO 1.2 MOLES OF DIARYL CARBONATE, AND FOR 50 TO 500 PPM OF A RESTERIFICATION CATALYST; SECOND, THE MIXTURE FORMED IS HEATED BETWEEN 100 AND 200 DEGREES AND AT A PRESSURE OF LESS THAN 140 MBAR, UNDER THE ELIMINATION OF THE HYDROXYL COMPOUNDS FORMED; THIRD, THE MIXTURE FORMED IS ADDED BETWEEN A 0.2 AND A 5 IN WEIGHT OF PHENOL; AND LASTLY, THE MIXING IS SUBJECT TO A TEMPERATURE COMPRISED BETWEEN 100 AND 200 DEGREES AND A PRESSURE COMPRISED BETWEEN 3 AND 260 MBAR. |
