| titleOfInvention | Process for preparing polycarbonate |
| abstract | A method for preparing polycarbonates by melt polycondensation of a dihydroxy compound and a diarylcarbonate compound in the presence of an alkaline catalyst is described. A branching quencher compound is added to an intermediate polycarbonate produced by the melt polycondensation reaction in an amount effective to inhibit or prevent the formation of branching species during a subsequent finishing process. Adding the branching quencher compound to the product of the melt polycondensation reaction produces finished polycarbonates with reduced branching species, high ductility and impact strength. |
