以可再生腰果酚和生物多元醇（甘油、二甘油酯、三甘油酯）为前体合成了一系列腰果酚基多臂丙烯酸酯（CGHA、CDHA、CTHA）。用FT-IR、H-1 NMR和GPC分别表征了腰果酚基丙烯酸酯的结构和分子量。合成的多臂腰果酚基丙烯酸酯用于制备紫外光固化薄膜和涂料。光固化膜具有较高的机械强度和良好的生物降解性。研究了涂膜的硬度、光泽度和附着力等重要性能。结果表明：高生物基含量的涂层具有良好的附着力、光泽度和耐酸性能；它与大豆油（AESO）基和聚酯丙烯酸酯相当。(C) 2015 Elsevier B.V.版权所有
A series of multi-arms cardanol-based acrylates (CGHA, CDHA, CTHA) were synthesized using renewable cardanols and bio-based polyols (glycerol, diglycerol, tripilyglycerol) as precursors. The structures and molecular weights of the cardanol-based acrylates were characterized by FT-IR, H-1 NMR and GPC, respectively. The synthesized multi-arms cardanol-based acrylates were used to produce UV-curable films and coatings. High mechanical strength as well as-good biodegradability of the UV-cured films was obtained. The important coating film properties, such as hardness, gloss and adhesion were also investigated. The results showed that the coatings with high bio-based content exhibit good adhesion, gloss and acid-resistance; which is comparable to the soybean oil (AESO)-based and polyester acrylate.
