The present invention provides a novel bisphenol compound of formula (I).
wherein R
1
and R
2
are the same or different and are independently either hydrogen or methyl at each occurrence. The present invention also provides a process for preparation of these bisphenol compounds starting from Cashew Nut Shell Liquid (CNSL); —a renewable resource material. The bisphenols prepared in the present invention can be utilized as difunctional monomers for the preparation of various polymers such as epoxy resins, polyesters, polyethersulfones, polyetherketones, polyetherimides, polyarylates, polycarbonates, etc.
本发明提供了一种新型的双
酚化合物,其
化学式为(I),其中R1和R2相同或不同,每次出现时均独立地为氢或甲基。本发明还提供了一种从腰果壳液(CNSL)开始制备这些双
酚化合物的方法,CNSL是一种可再生资源材料。本发明中制备的双
酚可以用作双官能团单体,用于制备各种聚合物,如环氧
树脂、聚酯、聚醚砜、聚
醚酮、聚醚
酰亚胺、聚芳酯、聚
碳酸酯等。
