摘要：
Based on eugenol (Eug), biologic monomers with two and three function-groups were synthesized and their polymerization reactions were investigated. Using eugenol and diisocyanate as raw material, a biological monomer (EUG- HDI) containing ammonia ester bonds in the middle and double bonds at both ends was prepared via ammoniesterification. A trifunctional monomer (TEU) was synthesized with eugenol and melamine chloride. Eug-HDI and TEU were proportionally copolymerized via olefin metathesis to obtain a series of copolymerized products. The structure and properties of the polymers were characterized and analyzed by FT-IR, 1H-NMR, GPC and DSC. The results show that the yields of euG-HDI and TEU monomers can reach 89% from Eug. The copolymerization activity of euG-HDI with TEU is much lower than that of their respective homo-polymerization. The glass transition temperature (Tg) significantly varies with the different copolymerization proportions. © 2023 Chengdu University of Science and Technology. All rights reserved.
