反応後反応液を赤外吸収分光法で分析した。反応液中にイソシアネートが存在すると、2200~2300cm-1に強いシグナルが観察されるはずであるが、以下の分析結果の通り、当該範囲にはシグナルは認められなかった。

その後、反応液を100℃で2時間真空乾燥に付して、目的物を定量的に得た(0.08g,0.21mmol[モノマー換算])。赤外吸収分光法による生成物の分析結果は、反応後反応液の分析結果とほぼ同じであった。また、生成物を溶解できる溶媒が見付からなかったが、懸濁液を1H NMRで分析したところ、少なくとも含フッ素アルコールのピークは確認されず、目的物から含フッ素アルコールが除去できていることが分かった。更に、得られた目的物は、図1の通り、着色の無い白色固体であった。
