Abstract
The present invention relates to a polysiloxane-polycarbonate copolymer and a method of manufacturing the same. More specifically, the present invention relates to a polysiloxane-polycarbonate copolymer in which the molecular weight of the siloxane monomer constituting the copolymer is maintained in a specifically high level and thus excellent low-temperature impact resistance can be achieved even with low siloxane content, and the viscosity of the copolymer is maintained in a low level and thus flowability and moldability can be improved; and a method of manufacturing the same.
