| titleOfInvention |
A process for the preparation of poly (ester-carbonate)s |
| abstract |
The invention relates to a process for the preparation of poly (ester-carbonate)snfrom the corresponding oligomers, using solid state polymerization process, whichncomprises mixing the desired oligomers in a suitable solvent or non-solvent,nadding a suitable catalyst to this mixture, refluxing the mixture for a period of 1 ton8 hours , removing the solvent by known methods, polymerization the oligomernmixture in the solid state either in presence of vaccum or under a flow of inert gasnat a temperature ranging between 180-240°C for a period of 5 to 20 hours tonobtain the product. |
