“…21 At present, researchers are committed to finding suitable biomass to prepare bio-based environmentally friendly plasticizers. Among them, the reported biomass resources that can be used as plasticizer raw materials are cardanol, [22][23][24] castor oil, [25][26][27] waste cooking oil, 28,29 vanillic acid, 30 2,5-furan dicarboxylic acid, [31][32][33] isosorbide, 34 rosin 35,36 and so on. By pre-considering the influence of plasticizer structure on the properties of polymer materials, researchers carried out planned group modification of biomass chemical raw materials to obtain various new high-efficiency bio-based plasticizers.…”
