METHOD OF DEPOLYMERIZING AROMATIC POLYCARBONATE |
摘要 |
<p>An aromatic polycarbonate depolymerization method comprising reacting an aromatic polycarbonate with water, an aliphatic alcohol having 1 to 6 carbon atoms or a phenol which may be substituted by a hydrocarbon group having 1 to 10 carbon atoms in the critical fluid of carbon dioxide or with the critical fluid of an aliphatic alcohol having 1 to 6 carbon atoms or a phenol which may be substituted by a hydrocarbon group having 1 to 10 carbon atoms. <??>With this depolymerization method, the aromatic polycarbonate is depolymerized at a high reaction rate and effective components formed by depolyemrization can be recovered at a high rate. Therefore, the effective components are recovered from the scrapped or used aromatic polycarbonate by this method and recycled.</p> |
