A novel photo initiator grafted styrene type thermoplastic elastomer in pressure-sensitive adhesives was prepared as follows. Firstly, 4-maleimidobenzophenone(MBP)was prepared by the reaction of maleic anhydride (MAH) and 4-aminobenzophenone (4-ABP) ;Then, MBP was grafted to the side chain of SBS using benzoyl peroxide(BPO)as an in-itiator,FTIR and NMR were used to characterize the synthesis of SBS-g-MBP and MBP, and the crosslinking degree was estimated by the gel-fraction content; At last, the UV curing adhesives was decorated by SBS-g-MBP, tackifier, intensifiers and antioxidant to felt kraft paper, the performance index of modifated pressure-sensitive adhesives reached the technical re-quirements of Chinese kraft paper pressure-sensitive adhesives tapes(HG/T 2480-92).
