| titleOfInvention | PROCEDURE FOR THE PREPARATION OF RAMIFIED POLYCARBONATES. |
| abstract | Process for the preparation of branched polycarbonates by the melt transesterification process from diphenols, diaryl carbonates and branching agents, if necessary with the use of catalysts, at temperatures between 80 ° C and 400 ° C and at pressures between 1,013.5 hPa (1 atm) and 0.01 hPa, characterized in that branching agents use trifunctional to hexafunctional aliphatic alcohols, chosen from pentaerythrite, or their ether generated by self-condensation dipentaerythrite, glycerin, 1,2,3,6-hexanotetrol and 2,5-dimethyl- 1,2,6-hexanotriol, in amounts of 0.05 mol to 2 mol per 100 mol of diphenol. |
