| titleOfInvention | The continuous print manufacture method of polycarbonate-poly organo alkyl copolymer |
| abstract | The invention provides a kind of economy and stably manufacture the method for polycarbonate-poly organo alkyl copolymer.Specifically, the continuous print manufacture method of a kind of polycarbonate-poly organo alkyl copolymer, it comprises operation (A), operation (B) and operation (C), wherein, operation (A): polymerization liquid is extracted out continuously or off and on from reactor, described polymerization liquid obtains by dihydric phenol based compound, carbonate precursor and organopolysiloxane being carried out being polymerized under the existence of the basic cpd aqueous solution and water-insoluble organic solvent; Operation (B): the polymerization liquid extracted out in operation (A) is separated into aqueous phase and water-insoluble organic solvent phase; Operation (C): after the water-insoluble organic solvent acidic aqueous solution be separated in operation (B) is washed, be separated into aqueous phase and water-insoluble organic solvent phase, control in the mode that the content of the polycarbonate in isolated aqueous phase in operation (C)-poly organo alkyl copolymer is below 2 quality %, and aqueous phase water-insoluble organic solvent isolated in operation (C) is carried out extracting and is extracted liquid, part or all of extraction liquid is recycled in operation (A). |
