Method for producing polycarbonate-polydiorganosiloxane copolymer |
| abstract |
Provided is a method for efficiently and stably producing a polycarbonate-polydiorganosiloxane copolymer excellent in transparency on an industrial scale without using a tertiary amine catalyst. A mixed solution containing an oligomer having a terminal chloroformate group is prepared by a reaction of dihydric phenol (I) and phosgene in a mixed solution of an organic solvent insoluble in water and an aqueous alkaline solution in advance. Next, hydroxyaryl-terminated polydiorganosiloxane (II) is added to the mixed solution to form a highly emulsified state, and the highly emulsified state is maintained, and the hydroxyaryl-terminated polydiorganosiloxane (II) and the oligomer are interfacially weighted. A polycarbonate-polydiorganosiloxane copolymer characterized by using a water-insoluble organic solvent in an amount of 12 moles or more per mole of dihydric phenol (I) without using a tertiary amine catalyst for the condensation. Manufacturing method. [Selection figure] None |
