Abstract
The polymerization of propargyl bromide. propargyl chloride, and propargyl alcohol by W-,Mo-, and Ti-based catalysts was studied. Transition metal chloride- EtAlC12 catalyst systems were found to be very effective in the viewpoint of polymer yield and molecular weight. The number-average molecular weight (Mn)s of poly (propargyl bromide) and poly (propargyl chloride) were in the range of 8,700 to 19.500 depending on the catalysts and polymerization conditions. The polymer structure was identified as the conjugated polyene containing each substituent (CH2Br, CH2Cl, CH2OH). The solubility behaviors and thermal properties of the resulting polymers were also discussed.

W-,Mo-,Ti-계 촉매에 의한 프로파길 브로마이드, 프로파길 클로라이드, 및 프로파길알코올의 중합에 관해서 연구하였다 전이금속클로라이드와 EtAlC12로 구성된 촉매가 중합수율이나 분사량면에서 매우 효과적이었다. 폴리(프로파길 브로마이드)와 폴리(프로파길 클로라이드)의 수평분자량(Mn)은 사용한 촉매와 조건에 따라 8,700에서 19,500이었다. 합성한 중합체의 구조는 각 치환기(CH2Br, CH2Cl, CH2OH)글 갖는 공액 폴리엔으로 밝혀졌다. 또한, 합성한 중합체들의 용해성과 열적성질에 관해서도 연구하였다.
