Process for preparing polycarbonate from dianhydrohexitol dialkyl carbonate |
| abstract |
The present invention relates to a process for preparing a polycarbonate having a glass transition temperature of 50 ° C or higher, comprising the steps of (1) introducing a monomer of formula (I) wherein R 1 and R 2 are the same or different alkyl groups into a reactor; (2) introducing into the reactor a mixture (B) of one or more cyclic diols, or a diol containing at least 20 mol% of a cyclic diol; (3) polycondensation of the monomer mixture comprising monomers (A) and (B) via ester exchange; And (4) recovering the polycarbonate formed during step (3).
