Abstract
Photocurable pentaerythritol modified hyperbranched acrylates were prepared from trimellitic anhydride, glycidyl methacrylate and pentaerythritol derivatives. Thermal stability obtained by using TGA showed that HBMA-1 was superior to others. Hardness, abrasion resistance and tensile strength of HBMA-1 showed that they were also superior to the others. Value of yellow index of HBMA-1 showed the lowest.

다양한 pentaerythritol 유도체에 대한 trimellitic anhydride와 glycidyl methacrylate를 반응하여 세 종류의 8관능광경화형 pentaerythritol 변성 초분지형 아크릴레이트를 합성하였다. TGA로 측정한 UV 경화필름의 열 안정성은 pentaerythritol에 ethoxylate 또는 propoxylate가 부가되지 않은 pentaerythritol 단독을 사용한 HBMA-1이 가장 우수하였다. 또한 HBMA-1은 경도, 내마모성 및 인장강도도 우수하였으며, 내후성 테스트에서도 황변 지수인 yellow index 값이 가장 낮은 결과를 보여주었다.
