초록

2,2,2-트리플루오로에톡시기 및 p-카르복시페닐기를 갖는 새로운 폴리포스파젠 공중합체를 합성하였다. ¹H-NMR 분석에 의하면 카르복시산 에스테르가 28몰% 함유되어 있음을 알 수 있었다. 이 카르복시산 에스테르기를 카르복시산으로 바꾸고 Ba(OH)₂와 Sr(OH)₂를 이용하여 중화반응시켜 이오노머의 형성 가능성을 검토하였다. 주사슬이 비교적 극성이기 때문에 비교적 높은 금속 이온농도(∼10mole %)에서 ionic cluster가 생김을 알 수 있었다. 이 이오노머들은 DMF 혹은 THF 등에 용해되었으며, T_g가 105∼108 ℃로 비교적 높았다.

A polyphosphazene copolymer containing both 2,2,2-trifluoroethoxy and p-carboxyphenyl units was newly synthesized. According to ¹H-NMR analysis carboxylic ester content of the polymer was 28 mole % , and the ester groups were converted to carboxylic acid. This polymer was neutralized using varying amounts of Ba(OH)₂ and Sr(OH)₂, and the possible formation of ionomers was studied. It was found that about one third of the carboxylic acid groups was necessary to be neutralized before the formation of ionic clusters. The ionomers were soluble in DMF and THF. They showed relatively high T_g values of about 110℃.
