Abstract
Bismaleimides(BISMI) containing ester linkages were prepared by the chlorinated N-(p-carboxyphenyl)maleimide and N-(p-hydroxyphenyl)maleimide. The photosensitive properties of BISMI were investigated via changes of the irradiation time. Benzil dimethyl ketal was used as a photoinitiator. The effect of photoinitiator onto BISMI increase in average as increasing photoinitiator concentration and irradiation time. The yield of residual film and image pattern and resolution also measured and discussed.
N-(p-carboxyphenyl)maleimide의 염소화물을 N-(p-hydroxyphenyl)maleimide와 반응시켜 중심에 에스테르 결합을 가지고 있는 bismaleimide(BISMI)를 합성하였다. 합성된 BISMI의 감광특성을 확인한 결과 사용된 benzil dimethyl ketal 광개시제의 농도와 자외선 조사량을 증가시킴에 따라 BISMI의 점도가 증가하는 경향을 보였다 또한 BISMI의 잔막수율의 변화와 화상형성능력 및 최소선폭을 검토하였다.
