제목 Synthesis of UV-Curable Poly(tetramethylene ether)glycol(PTMG) Polyurethane Acrylate(PUA) and their properties
초록 In this study, transparent and flexible PUA was polymerized using PTMG with excellent elongation and flexibility. UV-curable polyurethane acrylate (PUA) was polymerized by PTMG with three molecular weights and three polymerization methods. The polymerized PUA was qualitatively analyzed by Fourier transform infrared spectroscopy (FT-IR). Polymerized PTMG PUA was measured for photocuring kinetics via Photo-DSC. Furthermore, universal testing machine (UTM) was employed to measure PUA’s tensile strength, elongation of break and modulus. Finally we confirmed their film properties such as transparency and pencil hardness.
