METHOD OF PRODUCING HIGHLY POLYMERISED AROMATIC POLYCARBONATE RESIN Russian patent published in 2015 - IPC C08G64/04 C08G64/42 

Abstract RU 2551370 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing an aromatic polycarbonate resin and an aromatic polycarbonate resin obtained using said method. An aromatic polycarbonate is cross-linked with an aliphatic diol compound having a boiling point of 240°C or higher (preferably in amount of 0.01-1.0 mol per mol of the total amount of terminal groups of the aromatic polycarbonate), via a cross-esterification reaction in the presence of a cross-esterification catalyst at low pressure (preferably in the range of 13-0.01 kPa(abs) (100-0.01 Torr)).

EFFECT: high molecular weight of the aromatic polycarbonate resin while maintaining good quality of the resin.
