| titleOfInvention | PROCESS FOR PRODUCING COPOLYESTER-CARBONATE |
| abstract | SIMPLE AND ECONOMICAL PROCESS FOR THE PRODUCTION OF COPOLYESTER CARBONATE. IT CONSISTS: IN REACTING IN A SOLVENT SYSTEM, AT A FIRST PH LEVEL OF ABOUT 9-12, A DIPHENOL AND AN ACID DICHLORIDE TO FORM A REACTIONAL MEDIUM, THE MOLAR RATIO OF DIPHENOL TO ACID DICHLORIDE BEING BETWEEN APPROXIMATELY 90:10 AND 55:45; -A ADD A CHAIN LIMITER IN THE REACTIONAL ENVIRONMENT; -A ADJUST THE PH OF THE REACTIONAL MEDIUM TO A SECOND PH LEVEL OF APPROXIMATELY 4-7; -A ADD A CARBONATE PRECURSOR TO THIS REACTIONAL MEDIUM; -A ADJUST THE PH OF THIS REACTIONAL MEDIUM TO A THIRD PH LEVEL OF ABOUT 9-12; - TO CONTINUE THE ADDITION OF THE CARBONATE PRECURSOR UNTIL THE END OF THE REACTION; AND -A RECOVER A COPOLYESTER-CARBONATE FROM THE SOLVENT SYSTEM. APPLICATION TO THE MANUFACTURE OF COPOLYESTER-CARBONATE. |
