초록
하이퍼브랜치 폴리올(HBP-16, 32, 64)과 acrylic acid로부터 광경화형 하이퍼브랜치 아크릴레이트를 합성하였고, 그 물성을 조사하였다. TGA로 측정한 UV 경화필름의 열안정성은 관능기 수가 증가할수록 좀더 높은 온도로 이동하였다. 또한 아크릴 레이트의 관능기 수가 증가할수록 경도, 내마모성, 인장강도가 우수하였으며, 내후성 테스트에서는 아크릴레이트의 관능기수가 증가할수록 황변 지수 값이 증가하는 결과를 보여주었다.
Photocurable hyperbranched acrylates were prepared from acrylic acid and hyperbranched polyol (HBP-16, 32, 64). Physical properties of three kinds of photocurable hyperbranched acrylated were investigated. Thermal stability of UV cured film measured by TGA shifted to higher temperature with increasing of functionality of acrylate. Weathering test for UV cured film showed the value of yellow index increased with increasing functionality of acrylate.
