초록
다양한 carboxylic ester acrylate를 합성하기 위하여 다양한 산 무수물에 hydroxyallkyl acrylate인 2-hydroxyethyl acrylate(2-HEA)를 반응시켰다. 합성된 carboxylic ester acrylate에 지방족 에폭시 화합물인 1,4-butanediol diglycidylether를 반응시켜 광경화형 에폭시 아크릴레이트를 제조하였다. 점도는 산 무수물 중에서 phthalic anhydride를 사용하여 반응시킨 것이 가장 높았다. 산 무수물 중에서 hexahydrophthalic anhydride를 사용한 것이 비교적 다른 무수물을 사용한 것보다 경도, 인장강도가 우수하였으며, 유리전이온도가 높고 5% 무게 감소 온도도 높은 것으로 보아 열적으로 안정하다는 것을 알 수 있었다.
A variety of carboxylic ester acrylates was prepared from anhydrides and 2-hydroxyethyl acrylate. Photocurable epoxy acrylates were prepared from synthesized carboxylic ester acrylates and 1,4-butanediol diglycidylether. Physical properties such as hardness, yellowing, tensile strength and elongation were tested and compared as the structure of oligomer in cured-film differs. Viscosity was highest when phthalic anhydride was used. Hardness and tensile strength with hexahydrophthalic anhydride were better than with the other anhydrides. Glass transition temperature with hexahydrophthalic anhydride was higher than with the others. And 5% weight loss temperature with hexahydrophthalic anhydride was higher than with the others.
