A high performance liquid chromatography-mass spectrometric（HPLC-MS） method was developed for the simultaneous determination of nine phthalate esters（PAEs）in pressure-sensitive adhesive and its products.The sample was dissolved with ethyl acetate,and the PAEs were separated from polymer by using methanol. The extract was centrifugally separated for 5 min at a speed of 3 000 r/min，and the nine PAEs were separated on an Xterra Phenyl（150 mm×3.9 mm,5 μm） column by gradient elution using acetonitrile-water as the mobile phase at a flow rate of 1 mL/min，and quantitatively determined under selected ion monitoring（SIM）. Under the optimized conditions，the method showed a good linearity in the range of 0.1-10 mg/L for the nine PAEs. The limits of quantitation were 0.000 1% for DIBP，BBP，DEHP and DNOP,and 0.000 5% for DMP，DEP，DBP，DINP and DIDP. The established method was applied in the determination of three kinds of common pressure sensitive adhesives,e.g.hotmelt pressure-sensitive adhesive，solvent pressure-sensitive adhesive and emulsion pressure-sensitive adhesive. The results indicated that the recoveries ranged from 88% to 110% with relative standard deviations（RSDs） less than 6.1%. The method was reliable，sensitive and reproducible，and could meet the requirements of determination of PAEs in pressure-sensitive adhesive and its products.
