POLYCARBONATE COPOLYMER POSSESSING HIGH FLOW CHARACTERISTICS, METHOD FOR PRODUCING AROMATIC POLYCARBONATE RESIN HAVING HIGH MOLECULAR WEIGHT AND AROMATIC POLYCARBONATE COMPOUND Russian patent published in 2015 - IPC C08G64/18 C08G64/30 C08G64/40 

FIELD: chemistry.

SUBSTANCE: invention refers to a high-fluid polycarbonate copolymer, a moulded part with using this copolymer, a method for producing highly-polymerised aromatic polycarbonate resin and a polycarbonate resin composition for producing moulded sheet or film parts. The high-fluid polycarbonate copolymer is formed by a structural link produced from an aliphatic diol compound, and a structural unit produced from an aromatic dihydroxycompound, and has a structure presented by formula (III):

.

EFFECT: producing the polycarbonate copolymer characterised by a high fluidity, however a high molecular weight.
