| titleOfInvention | Method for the production of polycarbonate |
| abstract | The invention relates to a method for producing polycarbonate according to the transesterification of molten mass method, by reacting at least one aromatic dihydroxyaryl compound and a diarylcarbonate in the melt, at least in the presence of a catalyst. A carbonate forming reagent is used, said reagent containing: at least 99.9 % of a diarylcarbonate of general formula ArO(C=O)OAr 0.5 to 500 ppm of a hydroxyaromate of general formula ArOH - 2 to 300 ppm of arylurethanes of general formula ArO(C=O)NR<SUP>1</SUP>R<SUP>2</SUP> - 2 to 100 ppm in the sum of (methylaryl)arylcarbonates of general formula (CH3Ar<SUP>1</SUP>)O(C=O)OAr a maximum of 100 ppm in the sum of (aryloxy)aryl carboxylic acid derivatives of general formula Ar<SUP>2</SUP>O-Ar<SUP>3</SUP>COOZ<SUP>1</SUP> a maximum of 100 ppm in the sum of hydroxyaryl carboxylic acid derivatives of general formula Z<SUP>2</SUP>O-Ar<SUP>4</SUP>COOAr a maximum of 10 ppm in the sum of o,o`-biphenylene carbonate, dibenzofuran and biphenyldiol derivatives of general formula Z<SUP>3</SUP>OAr<SUP>5</SUP>-Ar<SUP>5</SUP>OZ<SUP>4</SUP> a maximum of 10 ppm in the sum of aryloxyhydroxyaryl derivatives of general formula Ar<SUP>6</SUP>OArOZ<SUP>5</SUP> a maximum of 10 ppm in the sum of halogenhydroxyaromate derivatives of general formula (X)<SUB>m</SUB>Ar<SUP>7</SUP>OZ<SUP>6</SUP> a maximum of 10 ppm in the sum of o-arylencarbonate, dihydroxyaromates and derivatives of general formula Ar(OZ<SUP>7</SUP>)<SUB>2</SUB> a maximum of 10 ppm of alkylarylcarbonates of general formula ArO(C=O)OR<SUP>3</SUP> - a maximum of 10 ppm in the sum of ethers of general formula ArOR<SUP>4</SUP> a maximum of 5 ppm chloroformic acid ester of general formula Cl(C=O)OArrespectively, a maximum of 1 ppm of benzofuran-1.3-dione, diphenyloxalate and p-Chlorbenzoate a maximum of 10 ppm total content of chlorine respectively, a maximum of 1 ppm of Pb, Cu, Zn, Pd, Sn and Ti, wherein Z<SUP>1</SUP> to Z<SUP>7</SUP> independently represent one or several elements from the group -H, -Ar or -(C=O)OAr, Ar, Ar<SUP>1</SUP> to Ar<SUP>7</SUP> independently represent an aryl radial, X represents -Cl or -Br, m represents a whole number from 1 to 3 and R<SUP>1</SUP> to R<SUP>4</SUP> independently represent a linear, cyclic or branched alkyl radial having 1-20 C-atoms, wherein R<SUP>1</SUP> and R<SUP>2</SUP> form, optionally together, a cycle. |
