| titleOfInvention | Linear polycarbonate and method for producing the same |
| abstract | An object of the present invention is to provide a linear polycarbonate having no branched structure and excellent flowability. A peak area corresponding to a mass spectrum of 314 measured by a pyrolysis gas chromatography method and containing substantially no residual methylene chloride, having a viscosity average molecular weight of 10,000 to 30,000 corresponds to a mass spectrum of 256. Is a linear polycarbonate resin having an area of 0.1% or less of a peak area, which is obtained by subjecting an aromatic dihydroxy compound and a carbonic acid diester to a transesterification reaction so that the reaction temperature in all reaction steps is 100 ° C. to 270 ° C. It is produced by adjusting the amount of the catalyst to 1.0 × 10 −3 to 1.0 × 10 −8 mol per 1 mol of the aromatic dihydroxy compound. [Selection diagram] None |
