| titleOfInvention | Method for producing polycarbonate |
| abstract | PROBLEM TO BE SOLVED: To provide a molded product having good moldability, thermal stability and mold corrosivity while maintaining excellent transparency and mechanical properties of a polycarbonate suitable for optical materials, and low birefringence. To provide a method for producing polycarbonate. SOLUTION: In the method for producing a polycarbonate by melt-polycondensing an aromatic dihydroxy compound and a carbonic acid diester, at least 8 0 mol% is (a) 1,1-bis (4-hydroxyphenyl) -3,3,5-trimethylcyclohexane and (b) 4,4 ′-(m-phenylenediisopropylidene) diphenol and / or A method for producing a polycarbonate comprising a specific proportion of 2,2-bis (3-methyl-4-hydroxyphenyl) propane, wherein a specific terminal terminator is added and the terminal is blocked. |
