초록

4-히드록시스티릴피리딘과 4-비닐벤질클로리드를 반응시켜 감광성 단량체로서 비닐벤질옥시스티릴피리딘(VSP)을 합성하였다. 5-20mol%의 VSP를 로진 moiety를 함유하는 메타크릴단량체와 라디칼 공중합하여 로진 moiety를 함유하는 몇가지 광경화성 고분자를 합성하였다. UV분광법으로 결정한 공중합체 중의 VSP의 함량은 5.3-17.3mol%정도였다. 이들 고분자의 수평균 분자량은 18000-28000정도였고 다분산지수는 1.8 정도였으며, 또한 유리전이온도는 150℃ 부근이였고 초기 열분해온도는 340℃ 정도였다. 이들 고분자는 자외선에 의해 비교적 빠르게 경화되었고, 이 광경화 반응은 UV분광법과 잔막수율법으로 분석될 수 있었다.

Vinylbenzyloxystyrylpyridine(VSP) as a photosensitive monomer was synthesized by the reaction of 4-hydroxystyrylpyrydine with 4-vinylbenzyl chloride. Photocrosslinkable polymers containing rosin moiety were then prepared by radically copolymerizing VSP with a methacrylic monomer having rosin moiety. In these copolymerizations, the VSP feed ratios of 5 to 20mol% were used. The contents of VSP units in the copolymers were determined by UV spectroscopy to be 5.3 to 17.3mol%. The number-average molecular weights of these polymers were in the range of 18000 to 28000 and the polydispersity indexes were about 1.8. The glass transition temperatures were about 150℃ and the initial decomposition temperatures were about 340℃. The polymers were relatively fast photocrosslinked and the photocrosslinking reaction could be traced by the UV spectroscopy and the residual yield method.
