초록

새로운 단량체형의 자외선흡수제를 triethylamine에서 2,4-dihydroxybenzophenone과 N-4-chlorocarbonylphenylmaleimide의 반응을 통하여 합성하였다. 이 자외선흡수제를 폴리프로필렌에 용융반응에 의해 그래프팅하였다. Maleimide의 그래프팅 수율은 IR 분광 데이터를 이용하여 결정하였다. 용융반응의 최적조건을 구하기 위하여 반응 온도 및 시간, 단량체의 농도의 변화에 대하여 그래프팅 수율을 구하였다. Weatherometer에서 IR 스펙트럼의 카보닐 지수를 이용하여 그래프트된 폴리프로필렌의 광산화 정도를 조사하였으며, 우수한 광산화 억제작용을 보였다.

A novel monomeric UV-absorber was prepared by the reaction of 2,4-dihydroxybenzophenone with N-4-chlorocarbonylphenylmaleimide in the presence of triethylamine. This reactive maleimide was grafted onto polypropylene (PP) by the thermal melt-processing in a mini-max-moulder. IR spectroscopic method was used for the quantitative determination of the extent of grafting of monomeric maleimide. To find the optimal reaction conditions, the dependence of reaction temperature and time and the concentration of monomeric UV-absorber was investigated on the grafting yields. The photooxidative effect of the grafted PP was evaluated in the weatherometer comparing to the PP mixed with UVabsorbers using the carbonyl index of IR spectrum. The grafted PP showed an excellent anti-photooxidative effect.

Keywords:melt-grafting;UV-absorber;maleimide;2,4-dihydroxybenzophenone.
