摘　　要：以2-羟基-4-甲氧基二苯甲酮(UV-9)和甲基丙烯酸缩水甘油酯(GMA)为原料,通过环氧基开环反应制备了二苯甲酮类中间体(UG),再与乙烯基硅油(ViSO)进行共聚,合成了二苯甲酮类有机硅型紫外线吸收剂(UVi)。原料、中间体和产物的红外谱图证明甲基丙烯酸缩水甘油酯中的环氧基开环后与2-羟基-4-甲氧基二苯甲酮中的羟基进行反应,得到了末端含有双键的中间体,中间体与乙烯基硅油共聚得到了二苯甲酮有机硅型产物。紫外光谱证明了合成的二苯甲酮类有机硅型紫外线吸收剂在286.64、327.97 nm处有强吸收,说明紫外线吸收剂对紫外线有较强的吸收能力和较好的光稳定性。Dibenzophenone intermediate(UG)was prepared by epoxy ring-opening reaction of 2-hy⁃droxy-4-methoxybenzophenone(UV-9)and glycidyl methacrylate(GMA).Dibenzophenone organosilicon ultra⁃violet absorber(UVi)was synthesized by copolymerization with vinyl silicone oil(ViSO)and UG.The infrared spectra of raw materials,intermediates and products proved that the epoxy group in glycidyl methacrylate re⁃acted with the hydroxyl group in 2-hydroxy-4-methoxybenzophenone after ring-opening to obtain the inter⁃mediate with double bonds at the end.Silicone-type products of benzophenone were synthesized by copoly⁃merization of intermediates with vinyl silicone oil.The ultraviolet spectra proved that the synthesized benzophe⁃none organosilicon ultraviolet absorber had strong absorption at 286.64 and 327.97 nm,which indicated that the ultraviolet absorber had strong absorption ability and good light stability to ultraviolet radiation.
