(아이오도메틸)트리메틸실란을 이용한 2-에티닐피리딘의 무촉매중합

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.
