通过腰果酚缩水甘油醚（CGE）与多酸的开环反应，腰果酚链段烷基侧链上的不饱和度发生环氧化反应，再将环氧基进行丙烯酸酯化反应，制备了多臂腰果酚基丙烯酸酯低聚物。这些丙烯酸酯通过紫外线辐射引发固化生产生物基涂层;然后详细表征涂层性能。采用凝胶渗透色谱法（GPC）、傅里叶变换红外光谱（FTIR）和质子核磁共振（1H NMR）对丙烯酸酯低聚物进行了全面表征。用实时红外光谱法研究了这些丙烯酸酯的紫外光固化行为，结果表明，丙烯酸酯不饱和度的转化率随着齐聚物官能度的增加而增加。将这些低聚物配制成UV可固化涂料，并评价涂料性能以测定硬度、附着力、耐化学性、光泽度和表面性能。热塑性塑料的固化性能
Multiarmed, cardanol-based acrylate oligomers were prepared via the ring-opening reaction between cardanyl glycidyl ether (CGE) and polyacids, followed by epoxidization of the unsaturation in alkyl side chains of cardanol segments, and acrylation of the resulting epoxy groups. Biobased coatings were produced from UV-radiation-initiated curing of these acrylates; the coating properties were then characterized in detail. The acrylate oligomers were fully characterized using gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), and proton nuclear magnetic resonance (1H NMR). The UV-curing behavior of these acrylates was determined using real-time IR. The results indicated that the conversion of acrylate unsaturation increased with increasing oligomer functionality. These oligomers were formulated into UV-curable coatings, and the coating properties were evaluated to determine hardness, adhesion, chemical resistance, gloss, and surface properties. The properties of cured thermos...
