Provided are a novel polyorganosiloxane capable of preparing copolycarbonate with improved weather resistance and flowability while maintaining the intrinsic physical properties of polycarbonate resin, and a copolycarbonate prepared by using the same.

Polyorganosiloxane, and copolycarbonate prepared by using the same

Disclosed are polycarbonate having high fluidity through inclusion of an aliphatic polyhydric alcohol-substituted diphenol compound in a polycarbonate backbone and a method of preparing the same. The polycarbonate is polymerized by comprising a diphenol mixture and a carbonate precursor, the diphenol mixture comprising an aliphatic polyhydric alcohol-substituted diphenol compound according to Formula 1 and a bisphenol compound.

Polycarbonate having high fluidity and method of preparing the same

Disclosed are a terminally modified polyoxyalkylene glycol which may dramatically improve color uniformity and machinability, when applied to a polycarbonate resin transmittance, a polycarbonate resin composition comprising the same, and a light guide plate manufactured using the same.
