초록

Glycerol diglycidyl ether와 acrylic acid를 반응하여 지방족 에폭시 아크릴레이트를 합성하였다. 반응 경과는 적외선 분광법, 라만 분광법과 1H NMR로 분석하였다. 합성한 에폭시 아크릴레이트의 전자선 조사에 의한 경화거동을 조사하기 위해 전자선 조사량에 따른 시료의 분광 분석과 유리전이온도 분석, 인장 특성 등을 분석하였다. 이를 통해 약 30 kGy 정도의 저조사량에서 충분한 경화가 이루어짐을 확인하였다. 또한 합성한 에폭시 아크릴레이트는 점도가 낮아 용매 사용 없이 코팅용으로 사용하기에 적합하며, 경화 시편이 높은 광학적 투과도를 가지고 있어 광학적 투명도를 요구하는 전자선 경화형 광학필름 코팅용에 적합할 것으로 생각된다.

We synthesized aliphatic epoxy acrylate monomer by the reaction of glycerol diglycidyl ether and acrylic acid. The reaction was monitored by FTIR, Raman spectroscopy and 1H NMR. Electron-beam (E-beam) curing behaviors of the synthesized monomer were studied by spectroscopic analysis, glass transition temperature, and tensile properties. We found that curing reaction was complete in a low dosage of ca. 30 kGy. The viscosity of monomer was a low enough for coating without using diluents and the cured sample was highly transparent, indicating that the monomer can be used for an E-beam curable coating material on transparent optical films.

Keywords:electron beam curing;aliphatic epoxy acrylate;transparent optical films;FTIR;raman spectroscopy.
