PROCESS FOR MANUFACTURING POLYCARBONATE FROM DERIVATIVES OF DIANHYDROHEXITOLS BEARING TWO ALKYL CARBONATE FUNCTIONS |
摘要 |
<p>A process for manufacturing polycarbonate includes:—a step (1) of introducing into a reactor a particular composition (A) of at least one dianhydrohexitol carbonate bearing two alkyl carbonate functions; a step (2) of introducing a diol or a mixture of diols (B); a subsequent step (3) of polycondensation by transesterification of the mixture of monomers including (A) and (B); a step (4) of recovering the polycarbonate formed during step (3).</p> |
