摘　　要：以腰果酚与4-溴甲基二苯甲酮为原料,合成了具有光引发活性的腰果酚衍生物,收率86%。该衍生物的光引发活性优于普通的二苯甲酮。在不加其它光引发剂的情况下,UV光照30 s该液体衍生物即可固化。该衍生物与腰果酚不同比例的混合物,也可进行UV固化,腰果酚含量越高,所需固化时间越长。膜的硬度为3H-5H,且具有较好的耐溶剂与耐酸碱性能,可望用于防腐漆中。A cardanol derivative（1） with photo-initiating activity has been synthesized in 86% yield using cardanol and 4-bromomethyl benzophenone as precursors.The photo-initiating performance of the derivative 1 is better than common benzophenone according to the results of the controlled experiments.The derivative 1 can be completely cured within 30 s under UV irradiation without the presence of any photoinitiator.Furthermore,the mixtures of the derivative 1 and cardanol with various ratios can also be cured under UV irradiation that the UV-curing time is prolonged up to dozens of minutes with the increase of cardanol content.The resulting cured films show relatively high hardness（3H-5H）,excellent solvent,acid and base resistance,which have potential application in anti-corrosion coatings.
