Abstract A method is provided for making silicone polycarbonate block copolymers and polycarbonate blends thereof having reduced haze. Silicone polycarbonate block copolymer formation is effected by using a phase transfer catalyst to generate polycarbonate oligomers having at least one terminal haloformate group followed by the late addition of hydroxyaryl terminated polydiorganosiloxane.
