New asymmetrically substituted poly(2-acetoxy-1,4-phenylenevinylene), PAPV and poly(2-mesyloxy-1,4-phenylenevinylene), PMSPV were prepared via water soluble precursor polymer route. They were characterized by DSC, TGA, UV/VIS and FT-IR. They were readily doped with $FeCl_3$ at room temperature. Precursor film of PMSPV could be readily stretched before or during the elimination, but that of PAPV could not be stretched. Conductivity of unstretched PAPV and PMSPV were 19.4S/cm and 0.26S/cm respectively. But uniaxially drawn film(draw ratio=6) of PMSPV gave a conductivity of 20.4S/cm along the draw direction. This conductivity value was increased 78times than that of unstretched PMSPV. From FT-IR investigations, the precursor film of PAPV was thought to be converted into poly(2-hydroxy-1,4-phenylenevinylene) by the elimination of acetxy group at some extent. But the precursor film of PMSPV did not change during the elimination.
폴리(2-아세톡시-1,4-페닐렌비닐넨), PAPV 와 폴리(2-메실옥시-1,4-페닐렌비닐렌), PMSPV 를 수용성 선중합체를 거쳐 필름 형태로 합성하였다. 필름의 구조 및 특성을 DSC, TGA, UV/VIS, IR 을 이용하여 연구하였다.
선중합체를 HCl 기체 촉매하에서 이들이 poly(2-hydroxy-1,4-phenylenevinylene),PHPV로 변하는지 여부와 그 정도를 조사하였다. 그 결과 PAPV의 선중합체는 어느 정도 변화하지만 PMSPV의 선중합체는 거의 변하지 않음을 관찰할 수 있었다.
최종 중합체를 상온에서 $FeCl_3$ 로 도핑하여 4-탐침법으로 전기 전도도를 측정하였다. 연산되지 않은 PAPV 는 19.4S/cm의 전도도를 보였고 PMPV 는 6배 연신되어, 연신하지 않은 필름에 비해 78배 정도 증가된 20.4S/cm의 전도도를 보였다.
