Method for producing polycarbonate |
| abstract |
The present invention provides a process for the preparation of (co)polycarbonates comprising reacting tetrabromo bisphenol A and optionally one or more bisphenol co-monomer(s) with phosgene, wherein tetrabromo bisphenol A is contains tetrabromo bisphenol A dimer in an amount of up to 3.0% by weight based on weight, which is determined after heat treatment of tetrabromo bisphenol A at a temperature of 260° C. for a period of 15 minutes . |
