Detecting stoichiometric end point in aromatic polycarbonate resin preparation |
| abstract |
A method for detecting the stoichiometric end point of a preparation of aromatic polycarbonate resin involving the use of phosgene and an organic solvent in which the phosgene is normally soluble which comprises detecting the increase of phosgene gas occurring in the vapor phase of the reactor at or following achievement of the stoichiometric end point of the aromatic polycarbonate preparation. |
