Tung oil anhydrides（TOM1∽TOM3）and tung acid anhydrides were synthesized via the Diels-Alder reaction of tung oil、tung acid with maleic anhydride (MA).Under the catalysis of triethylamine, TOM and TAM molecules were reacted with the hydroxyl groups of Irgacure2959 to produce four photo-cleavage photoinitiators (TOMG1∽TOMG3, TAMG).The structure of initiator was characterized by FT-IR and 1H NMR spectroscopy. The Photo bleach of prepared photoinitiator was analyzed by UV visible spectroscopy. The photopolymerization dynamics of 1, 6-hexanediol diacrylate initiated by prepared photoinitiator or Ingancure2959 were studied by real-time FT-IR technology. The results show that TOMG3 has the best photo initiated performance with respect to Irgacure2959 and the synthesized tung oil-based photoinitiators. The UV curing gum of HDDA,、PUA and TOMG3 in a mass ratio of 46: 46: 8 (effective photoinitiator group content 2.14 wt%) were cured under irradiation of 28mW/cm2UV lamps in 60 seconds with gel rate of 96%. The hardness and flexibility of curing film was 6H and 5mm, respectively. The adhesion to the glass was zero level.
