  • BIO-BASED POLYARYLENE ETHER RESIN CONTAINING FURAN RING STRUCTURE AND PREPARATION METHOD THEREFOR
    Publication number: 20210047466
    Abstract: The present invention relates to the technical field of polymer science, and disclosed thereby is a bio-based polyarylene ether resin containing a furan ring structure and a preparation method thereof. A bio-based monomer containing a furan ring structure furan-2,5-bis(4-fluorophenyl)methanone (BFBF), which is inventively prepared by using a bio-based derivative furan dicarboxylic acid (FDAC), undergoes a nucleophilic substitution reaction with one or more from a dihydric phenol monomer and a dihalobenzophenone monomer to prepare a bio-based homopolymerized or copolymerized polyaryletherketone resin containing a furan ring structure. The introduction of a bio-base into the field of special engineering plastics diversifies the types of polyaryletherketone resins, while also effectively responding to an oil crisis.
