Abstract
The polymerization of propargyl phenyl ether(PPE) was carried out by various transition metal catalysts. MoCl5-based catalysts were more effective than WCl6-based catalysts. (n-Bu)4Sn was found the be very effective cocatalyst for the polymerization of PPE by MoCl5. It was found that 1,2-di-chloroethane, toluene, chlorobenzene are good solvents for this polymerization. The resulting poly (propargyl phenyl ether) [poly(PPE)] structure was identified by NMR, IR, UV-visible spectroscopies to have highly conjugated polyene structure. The poly(PPE) was completely soluble in aromatic and halogenated hydrocarbons such as benzene, chlorobenzene, and chloroform, but insoluble in methanol, formic acid, and hexane. The poly(PPE) was thermally stable up to 200℃.

여러 가지 전이금속촉매를 사용하여 프로파길 페닐 에테르(PPE)를 중합시켰다. MoCl5계 촉매가 WCl6계 촉매보다 훨씬 더 효과적이었으며 MoCl5를 사용한 PPE의 중합에서 (n-Bu)4Sn이 매우 우수한 조촉매로 밝혀졌다. 본 중합에 적합한 용매는 1,2-디클로로에탄, 톨루엔, 클로로벤젠등이였으며 NMR, IR, UV-visible 분광분석에 의해 합성한 중합체의 구조를 분석한 결과 공액 폴리엔 구조를 가지고 있음을 알 수 있었다. 폴리(PPE)는 벤젠, 클로로벤젠, 클로로포름과 같은 방향성 및 할로겐이 포함된 탄화수소 용매에는 완전히 녹는 반면 메탄올, 개미산, 헥산 등에는 용해하지 않았다. 열중량분석 결과 폴리(PPE)는 200℃까지 안정함을 알 수 있었다.
