Abstract:

The type-I cardanol with allyl ester group(GMA-C) was synthesized by the reaction of cardanol and glycidyl methacrylate(GMA), and further reacted with methacrylic anhydride(MAA) to prepare the type-II cardanol with allyl ester group (MAA-GMA-C). The chemical structure of the products were characterized by FT-IR, 1H NMR and 13C NMR. The UV curing properties of the prouducts, mechanical properties and chemical resistance of the cured film were investigated. The results showed that the cardanols with allyl ester group could be cured under UV irradiation for 40 s, the pencil hardness of the film could reach 4H, the adhesion force could reach grade two, and the cured film had better properties of water resistance, ethanol tolerance and acid resistance.

Key words: cardanol, glycidyl methacrylate, UV curing, synthesis, property
