The polymerization of N-methyl-3-ethynylcarbazole(NMEC) and N-propargyl-carbazole(NPC) was attempted by transition-metal catalysts under various reaction condition. In the polymerization of NMEC, the catalytic activity of WCl₆ was greater than that of MoC1₅, but MoC1₅ was more effective than WCl₆ for the Polymerization of NPC. Zieg1er-Natta catalysts were also uses. The polymer structures were characterized by various spectroscopic methods(¹H-NMR, IR, and UV-Visible Spectroscopy). Poly(NMEC) was soluble in polar aromatic and halogenated solvents such as chloroform, chlorobenzene, 1,2-dichloroethane but insoluble in methanol and ethyl ether. On the other hand, Poly(NPC) was insoluble in any organic solvents. Poly(NMEC) and poly(NPC) did not show weight loss up to 220℃ and 300℃ under nitrogen atmosphere, respectively. The electrical conductivities of I₂-doped poly(NMEC) and poly(NPC) were 8.0×10^-3Ω^-1cm^-1 and 1.2×10^-5Ω^-1cm^-1, respectively.

전이금속촉매를 사용하여 여러반응조건하에서 N-메틸-3-에티닐카르바졸과 N-프로파길카르바졸의 중합을 시도하였다. N-메틸-3-에티닐카르바졸의 중합에서는 WCl₆가 MoCl₅보다 효과적이었고 N-프로파길카르바졸의 중합에서는 MoC1₅가 WCl₆보다 더 효과적이었다. Ziegler-Natta 촉매도 중합에 사용하였다. 합성한 고분자의 구조는 ¹H-NMR, IR, UV스펙트라로 확인하였다. 폴리(N-메틸-3-에티닐카르바졸)은 클로로포름, 클로로벤젠, 1,2-디클로로에탄에는 완전히 용해되고 메탄올, 에틸에테르에는 녹지않았다. 폴리(N-프로파길카르바졸)은 유기용매에 녹지 않았다. 폴리(N-메틸-3-에티닐카르바졸)과 폴리(N-프로파길카르바졸)을 열중량분석 결과 각각 220℃와 300℃까지 무게감소가 없었다. 요오드로 도핑한 폴리(N-메틸-3-에티닐카르바졸)과 폴리 (N-3-프로파길카르바졸)의 전기전도도는 8.0×10^-3Ω^-1cm^-1로 나타났다.
