초록
본 논문은 큰 치환기인 메틸렌 트리메틸암모늄 테트라페닐보레이트를 치환기로 갖는 공액구조 고분자인 폴리(프로파길 트리메틸암모늄 테트라페닐보레이트)의 합겅과 그 특성조사에 관한 연구내용을 다룬 것이다. PdCl22 PtCl2, RuCl3 등의 전이금속 촉매를 사용해서 중합시켰을 경우 중합반응이 잘 진행되었으며 비교적 높은 수율(67-99%)의 중합체를 얻을 수 있었다. 합성한 중합체는 그 합성방법에 관계없이 유기용매에 대부분 용해하지 않았으며 갈색 혹은 검은색의 분말상이었다.본 중합체 구조에 대한 기기분석 결과 이 고분자는 치환기로 메틸렌 트리메틸암모늄 테트라페닐보레이트를 갖는 공액구조 고분자임을 확인할 수 있었바. X-선 회절분석 결과 본 중합체는 대부분 무정형임을 알 수 있었다.
This paper deals with the synthesis of poly(propargyl trimethylammonium tetraphenylborate) having a highly bulky substituent, methylene trimethylammonium tetraphenylborate on the acetylene carbon, and its characterization. The polymerizations of propargyl trimethylammonium tetraphenylborate using transition metal catalysts including PdC12, PtCl, RuC13, etc. were proceeded well to give a relatively high yields of polymer (67-99%). The resulting polymers were mostly insoluble in common organic solvents, and separated as a brown and black solids. Instrumental analyses on the polymer structure suggested that the resulting polymer had a conjugated polymer backbone with the methylene trimethylammonium tetraphenylborate substituent. X-ray diffraction analysis revealed that the polymer is amorphous.
