| titleOfInvention | Method for preparing solid state polycarbonates in a unitary series of operations |
| abstract | Amorphous precursor polycarbonates, such as oligomers, are converted to high molecular weight polycarbonates in a unitary series of operations that includes contact with an alkanol having a boiling point up to about 180 °C and heating the resulting wetted particles so as to effect solid state polymerization. Heating is at progressively increasing temperatures from below the boiling point of the alkanol to a final level between the Tg and the melting temperature of said enhanced crystallinity polycarbonate. |
