Novel UV curable multi-functional polyurethane acrylate (PUA) containing 3-(2-hydroxyethyl) isocyanurate (THEIC) segment was synthesized through three step reactions, the ring-opened reaction of e-caprolactone with THEIC under the catalysis of tetrabutyl titanate (TBT). the polyaddition reaction between formed hydroxyl compounds and isophorone diisocyanate (IPDI) and condensation reaction between the product of the second step and pentaerythritol triacrylate (PETA). The chemical structure of PUA oligomer and some influence factors in synthesis process were characterized with GPC, H-1 NMR and FTIR. And its photopolymerization process and properties of cured films were also investigated. (C) 2009 Elsevier B.V. All rights reserved.
