Four novel fluorine-containing triazine ultraviolet absorbers(FTUA)were synthesized and characterized by 1H-NMR and FT-IR.The UV absorption was studied in 3×10-6M N,Ndimethylformamide(DMF)by ultraviolet spectrophotometer,which revealed that FTUA have excellent UV absorption.The surface enrichment performance in polyvinyl chloride(PVC)was evaluated by contact angle measurement and photo-degradation.
