지방족 에폭시 수지인 glycerol diglycidyl ether (GDE)에 단관능성 아크릴 수지인 2-carboxyethyl acrylate (2-CEA) 또는 2-hydroxyethyl acrylate (2-HEA)를 반응시켜 지방족 에폭시 아크릴레이트를 제조하였다. FT-IR,1H-NMR, 그리고 13
C-NMR를 사용하여 생성물을 확인하였고, 수율은 prep-LC를 사용하여 얻었다. 생성물의 자외선 경화거동은 photo-DSC를 사용하였고, 열경화 반응성은 DSC를
사용하여 얻었다. 2-CEA의 반응성이 2-HEA보다 월등히 높음을 알 수 있었고, 2-CEA로부터 제조한 지방족 에폭시 아크릴레이트(GEA-C)의 수율은 약 83%이었다. 촉매를 제거한 GEA-C 생성물의 자외선 경화반응(Tmax)은 약 10 s로 빠르게 진행되었다. GEA-C는 투명하고, 내열성이 우수하며 저점도를 갖고 있음을 확인할 수 있었다. △E*는 2.51, 점도는 192 cps, 5% 중량감소 때의 온도는 299°C이었
다. Kissinger와 Ozawa-Flynn-Wall 식으로 얻은 GEA-C의 열경화 반응의 활성화에너지(Ea)는 91∼92kJ/mol이었다.UV-curable aliphatic epoxy acrylates were prepared by the reaction of glycerol diglycidyl ether(GDE) with 2-carboxyethyl acrylate (2-CEA) or 2-hydroxyethyl acrylate (2-HEA). The structures of the epoxy acrylates were characterized by FT-IR, H-NMR, and 13C-NMR and the yield was obtained by prep-LC. The UV- and the thermal-curing behaviors of the product were investigated using photo-DSC and DSC, respectively. The reactivity of 2-CEA was higher than 2-HEA and the yield of the product (GEA-C) which was
prepared using 2-CEA was about 83%. The maximum UV-curing time (Tmax) of the GEA-C contained non-reactive components and by-product was about 10 seconds. The GEA-C showed low color difference (△E*), low viscosity, and good thermal stability - its value was 2.51, 192 cps, and 299°C (at 5% weight loss), respectively. The activation energies (Ea) of thermal-curing reaction calculated from Kissinger and Ozawa-Flynn-Wall method were 91∼92 kJ/mol.
