摘　　要：以二烯丙基双酚A制备了烯丙基苯并噁嗪(BA-mt),系统研究了基于硫醇-烯烃点击反应的烯丙基苯并噁嗪/三羟甲基丙烷三丙烯酸脂/三羟甲基丙烷三(3-巯基丙酸酯)(BA-mt/TMPTA/TMPMP)紫外光固化体系的机械性能和热性能。结果表明:紫外光固化树脂BA-mt/TMPTA/TMPMP的硬度和耐磨性随着BA-mt含量的增加而提高;随BA-mt用量的增加光固化膜的玻璃化转变温度也不断提高;光固化膜具有良好的耐热性能,光固化膜的初始热分解温度和残炭率都随着BA-mt含量的增加逐渐提高。当BA-mt含量为20%时,BA-mt/TMPTA/TMPMP光固化膜的铅笔硬度(6H)和耐磨性最好,玻璃化转变温度和初始热分解温度分别达到12.4℃和353℃。Allyl-terminated benzoxazine（BA-mt）was synthesized from 2,2′-diallylbisphenol A.The mechanical and thermal properties of thiol-ene system of allyl-terminated benzoxazine（BA-mt）/trimethylolpropane triacrylate（TMPTA）/trimethylolpropane tris（3-Mercaptopropionate）（TMPMP）were investigated.The results showed that the pencil hardness and abrasive resistance of cured films increased with increase the BA-mt content.The glass transition temperature of cured film increased with the increase of BA-mt content,and the initial decomposition temperature and char yield were significantly enhanced with incorporation of BA-mt.When the content of BA-mt was 20%,the cured film had highest pencil hardness（6H）and the best abrasive resistance.The glass transition temperature and initial decomposition temperature were 12.4℃and 353℃ respectively.
