“…With the revival of bio‐based materials, the design and synthesis of new bio‐based monomers and bio‐based polymers is ongoing in sustainable chemistry 15 . By using traditional and new polymerization methods, such as melt condensation polymerization, free radical polymerization, enzyme catalyzed polymerization, and so forth, bio‐based monomers can be converted into various bio‐based polymers, including polyester, polyamide, polycarbonate, and so forth 16 . The researches show that bio‐based polymers have excellent mechanical and thermal properties, and other good features, such as shape memory and self‐healing functions, which are expected to replace traditional petroleum‐based polymers 17 .…”

The synthesis of bio‐based modified amphoteric epoxy modified acrylate sizing emulsion based on reversible addition fragmentation chain transfer (RAFT) polymerization and its application in paper sizing were studied. A macromolecular chain transfer agent for RAFT polymerization was synthesized by the esterification of epoxy resin E‐51 with RAFT agent to eliminate the active groups on RAFT agent. Amphoteric polymer emulsifiers with good emulsification and dispersion effects in acidic and alkaline media were successfully prepared by RAFT polymerization. After neutralization, other monomers were polymerized to access cationic sizing emulsion (acid neutralization) and anionic sizing emulsion (alkali neutralization). The effects of bio‐based monomer content, hydrophilic monomer dimethylaminoethyl methacrylate (DM) content and degree of quaternization on the properties of sizing emulsion and sizing paper were further explored. In addition to the particle size and polymer dispersion index (PDI) of latex particles in different experimental groups, the water resistance, folding resistance, bursting strength, tensile strength and surface roughness of sized paper were analyzed and evaluated. Based on these results, a better sizing emulsion formulation was established. It was confirmed that the addition of bio‐based monomers can improve the sizing performance of paper.
