Production method for aromatic polycarbonate resin having increased molecular weight |
| abstract |
The present invention provides a process for preparing a highly polymerized aromatic polycarbonate resin which not only has excellent quality such that it has high molecular weight and high fluidity, but also has more excellent heat resistance. The process of the present invention comprises a highly polymerizing step for reacting an aromatic polycarbonate prepolymer with an aliphatic diol compound of the following formula (I) having hydroxymethyl groups (HO-CH 2 -) each bonded to a quaternary carbon atom in the presence of a transesterification catalyst to obtain a highly polymerized aromatic polycarbonate resin:n nwherein Ra to Rf, n, and m are as defined in the present specification and claims. |
