Abstract

A new ionic polyacetylene with the substituent of N-(trimethylsilylmethyl)pyridinium iodide was synthesized by the non-catalyst polymerization of 2-ethynylpyridine using (iodomethyl)trimethylsilane). The polymerization proceeded heterogeneously to yield 95% of polymer. However, the resulting polymer was insoluble in most organic solvents due to the cross-linking reaction during polymerization. The polymer structure was characterized to have a conjugated backbone system with the designed ionic pyridyl substituents. The thermal and morphological properties of the polymer were measured and discussed.

초록

(아이오도메틸)트리메틸실란을 이용한 2-에티닐피리딘의 무촉매 중합을 통하여 N-(트리메틸실릴메틸) 피리디늄 아이오다이드를 측쇄로 갖는 새로운 공액구조 고분자를 합성하였다. 이 중합반응은 불균일하게 진행되었으며 중합수율은 95%로 매우 높았지만 생성된 고분자는 중합중 가교화반응으로 대부분의 유기용매에 용해하지 않았다. 합성 고분자의 분자구조를 분석한 결과 이온성 피리딜 치환기를 갖는 해당 고분자가 합성 되었음을 확인할 수 있었다. 합성 고분자의 열적 특성과 몰폴로지 등을 TGA, EDX 등의 분석장비로 측정하고 분석하였다.
