The invention discloses a polycarbonate and a synthesis method thereof, a rigid monomer and a preparation method thereof. The polycarbonate comprises a structural unit represented by the following formula (i): (i); at the same time, the structure shown in formula (I) can also be used: The synthesis of the polycarbonate not only makes the synthesized polycarbonate overcome the defects of the existing polycarbonate BPA-PC, but also is biodegradable, easy to realize the diversification of structure and function, good weather resistance, and has the potential of industrialization. Environmental protection requirements; in particular, the rigid monomer of the present invention can be prepared by using bio-based materials such as citric acid, the raw materials are widely sourced, inexpensive, renewable, and can reduce the dependence on petroleum resources from the source, which is conducive to industrial application. |
