초록

트리메틸암모니늄브롬마이드를 촉매로 사용하여 abietic acid와 glycidylmethacrylate를 메틸에틸케톤 중에서 반응시켜 로진 moiety를 함유하는 아크릴단랑체 (AMR)을 합성하였다. AMRDMF 5-20 mol%의 감광성 단량체 cinnamoyloxymethylmaleimide (COMMI)와 라디칼 공중합하여 rosin moiety를 함유하는 몇 가지 광경화성 고분자를 합성하였다. UV 분광법과 원소분석으로 결정된 공중합체중의 COMMI함량은 4.6-21 mol%정도였다. 이들 고분자의 수평균 분자량은 20000-28000 정도였고 다분산지수는 1.8 정도였으며, 또한 이들 고분자의 유리전이온도는 140-175 ℃였고 초기 열분해온도는 250 ℃정도였다. 이들 고분자의 광경화반응은 UV분광법과 잔막 수율법으로 추적될 수 있었다.

Rosin moiety-containing monomer(AMR) was synthesized by reacting abietic acid and glycidylmethacrylate in methylethylketone using trimethylammonium bromide as a catalyst. Photocrosslinkable polymers containing rosin moiety were then prepared by radically copolymerizing AMR with cinnamoyloxymethylmaleimide(COMMI) as a photosensitive monomer. In these copolymerizations, the COMMI feed ratios of 5 to 20 mol% were used. The contents of COMMI units in the copolymers were determined to be 4.6 to 21 mol%. The number-average molecular weights of these polymers were in the range of 20000 to 28000 polydispersity indexes were about 1.8. The glass transition temperatures were ranged between 140 and 175 ℃, and the initial decomposition temperatures were about 250 ℃. In addition, the photocrosslinking reaction of these copolymers could be traced by the UV spectroscopy and the residual yield method.
