Method for producing branched polycarbonate with molecular weight control and branched polycarbonate produced thereby |
| abstract |
The present invention relates to a process for producing a branched polycarbonate capable of controlling the molecular weight and a branched polycarbonate produced thereby, and the branched polycarbonate of the present invention is a process for producing a branched polycarbonate having a molecular weight regulated by reacting bisphenol A, diphenyl carbonate, Preparation step S10; An injecting step S20; Heating step S30: first pressure reducing step S40; A second pressure reducing step (S50); And a final depressurization step (S60), wherein the molecular weight adjuster is dispersed over three steps. Accordingly, the present invention provides a branched polycarbonate suitable for use in a large-sized injection molding such as a semiconductor wafer transportation container, since the average molecular weight and the molecular weight distribution are controlled and the impact characteristics and the processing characteristics are improved. |
