Phosphonated and methacrylated biobased cardanol monomer: Synthesis, characterization and application

To create an effective adhesion promotion for different surfaces, specific anchor groups are necessary such as phosphonic metals. Biobased phosphorylated monomer from cardanol was synthesized and polymerized by UV curing or miniemulsion radical polymerization. Phosphonic ethoxy methacrylate (CMP) via hydroxyethylation, followed phosphorylation addition of dimethyl phosphite onto the unsaturations C15 aliphatic chain prior methacrylation hydroxyl group. Lastly cleavage phosphonate ester made to generate targeted acid moieties promoters. Moreover, development a latex successfully achieved copolymerization in water with additional redox termination ensure quantitative conversions. (as reference) latexes were characterized dynamic light scattering. The effects derivatives on performance protective coatings steel plates evaluated UV-cured well terms contact angle effectiveness. In coatings, increased hydrophobic properties observed fomulations containing free methacrylate. On other side, incorporation significantly improved effectiveness coating, whatever film-making technique.
