Abstract: The allyl glycidyl ether modified cardanol(AGE-C) was prepared via reaction of cardanol with allyl glycidyl ether, and then the AGE-C was reacted with methacrylic anhydride to form allyl cardanol with ether bond and ester bond(MAA-AGE-C). The chemical structures of AGE-C and MAA-AGE-C were characterized by FT-IR, ¹H NMR and ¹³C NMR. The results showed that the optimum conditions for the synthesis of allyl ether modified cardanol were as follows:the molar ratio of allyl glycidyl ether to cardanol was 1.2:1, the dosage of potassium hydroxide was 1% of the mass of cardanol, and the conversion of cardanol hydroxyl could reach over 95% at 100℃ for 2 h. The optimum conditions for the synthesis of allyl cardanol with ether bond and ester bond were as follows:the molar ratio of methacrylic anhydrideallyl to ether modified cardanol was 1.2:1, the dosage of 4-dimethylaminopyridine was 2% of AGE-C by mass, and the conversion of AGE-C hydroxyl could reach over 93.5% at 90℃ for 3 h. The hydroxyl and iodine values of AGE-C and MAA-AGE-C were 154 mg/g, 10 mg/g, 2.4 g/g and 2.1 g/g, respectively.
