1-(1', 3'-Pentadienyl)-2,2,3,3-tetracyanocyclopropane(2) was prepared by the reaction of bromomalononitrile with 1,1-dicyano-1,3,5-heptatriene(1). Compound 1 was prepared from 2,4-hexadienal and malononitrile. Monomer 2 was polymerized by anionic initiators such as sodium cyanide to give the polymer 3 with pentadienyl functionalities in the pendant group. The resulting polymer was soluble in acetone and the inherent viscosities were in the range of 0.05∼0.10dL/g.

브로모말로노리트릴과 1,1-디시아노 1,3,5-헵타트리엔(1)을 반응시켜 1-(1',3'-펜타디에닐)-2,2,3,3-테트라시아노시클로프로판(2)을 합성하였다. 화합물 1은 2,4-헥사디에날과 말로노니트릴로부터 합성하였다. 단량체 2를 시안화 나트륨과 같은 음이온 개시제로 중합시킨 결과 시클로프로관고리가 개환되어 펜타디에닐기가 치환된 중합체(3)을 얻었다. 중합체 3은 아세톤에 녹았으며 고유점도는 0.05∼0.10dL/g을 보였다.
