Cyanuric chloride was used as raw material to synthesize two new bifunctional light stabllizer which have hindered amine structure——2-phenyl-4,6-[2- hydroxyl-4-(2,2,6,6- tetramethylpiperidin-4-yloxycarbonylmethoxy)phenyl]-1,3,5- triazine（Ⅳa）and 2-phenyl-4,6-[2- hydroxyl-4-(1,2,2,6,6-pentamethylpiperidin-4-yloxycarbonylmethoxy)phenyl]-1,3,5- triazine（Ⅳb） via Grignard reaction,Friedel-craft reaction,Etherification reaction and transesterification reaction.The yield of Ⅳa and Ⅳb for 37.6% and 38.1%,respectively.The structures of target compounds were characterized by FTIR,MS and 1HNMR. Ultraviolet absorption performance of target compounds was tested.The result show that target compounds have strong absorption in 270~400nm.Maximum molar absorption coefficient(εmax) of compounds Ⅳa and Ⅳb was 6.6513?04（276nm），2.8374?04（339nm）L?mol-1? cm-1 and 6.4359?04（276nm），2.6483?04（339nm）L?mol-1? cm-1
