WEATHERABLE POLYCARBONATES COMPRISING OXANILIDE STRUCTURAL UNITS, METHOD, AND ARTICLES MADE THEREFROM

摘要

In one embodiment, the present invention be it is a kind of containing derived from least one dihydric phenol, carbonate precursor, component and at least one to be selected from oxanilide include compound, oxamate compound and its mixture. In another embodiment, the present invention is that a kind of prepare a kind of containing oxanilide is selected from derived from least one dihydric phenol and at least one component includes compound, oxamate compound, with its mixture, its contact procedure under reactive conditions at least one dihydric phenol, carbonate precursor, component and at least one to be selected from oxanilide include compound, oxamate compound and its mixture. In yet another embodiment, it include policarbonate includes oxanilide structural unit that the present invention, which is a kind of,. In yet another embodiment, the present invention be a kind of oxanilide prepared symmetrically or non-symmetrically include the steps that dihydric phenol include the aromatic amine that the petite person of contact contains hydroxyl and each of diaryl oxalate or its each alkyl having by at least one electron-withdrawing group. In yet another embodiment, the present invention be a kind of manufacture oxamate monohydric phenol include the contact procedure aromatic amine that contains hydroxyl and each of diaryl oxalate or its each alkyl having by at least one electron-withdrawing group.
