The present invention relates to a polycarbonate-polysiloxane copolymer containing a polysiloxane unit represented by the following formula (1). The polycarbonate-polysiloxane copolymers of the present invention have good melt flow and ductility properties while maintaining high transparency and low haze: [Chemical Formula 1] Wherein R 1 and R 2 are each independently a C1-C10 alkyl group, a C6-C18 aryl group, a C1-C10 alkyl group or a C6-C18 aryl group substituted with a halogen or alkoxy group, and each X is independently C1-C10 Alkyl group or C6-C18 aryl group, n is an integer from 20 to 100). |
