Description
例1:イソシアネートの3−イソプロペニル−α,α−ジメチルベンジルイソシアネートをベースとし、炭酸セシウムを用いた、ビス[3−イソプロペニル−α,α−ジメチルベンジル]カルボジイミドの製造(本発明実施例)。
例2〜6:イソシアネートの3−イソプロペニル−α,α−ジメチルベンジルイソシアネートをベースとし、他の触媒を用いた、ビス[3−イソプロペニル−α,α−ジメチルベンジル]カルボジイミドの製造(比較例)。
30gの3−イソプロペニル−α,α−ジメチルベンジルイソシアネートを、内部温度計、還流冷却器および保護ガス入口を取り付けた100mLの3口フラスコの中に秤込み、次いで、0.6g(2重量%)の、表1に記載のそれぞれの触媒を添加した。アルゴン保護ガスの気流を加熱相中の蒸気相の上に通した。CO2の発生が開始されたら、保護ガスは停止した。その混合物を、195℃で3.5時間激しく撹拌し(例1〜5)、次いで約100℃までそれが冷却されたら直ちにその反応混合物濾過した。収率は、1H NMR分光光度法(400MHz、CDCl3)により求めた。
この目的のために、1.0重量%/1.5重量%の本発明によるカルボジイミド(CDI inv)および市販のカルボジイミド:
CDI 1=アルキル基で置換されたモノマー性芳香族カルボジイミド
CDI 2=ポリマー性芳香族カルボジイミド
を、市販のポリエステルベースの熱可塑性ポリウレタンエラストマー(TPU/Desmopan(登録商標)2587A)の中に、2軸スクリューエクストルーダーを使用した押出し加工によって組み入れた。
例7:
Evonik AGから入手可能な一級ヒドロキシル官能基を有し、3500g/molの平均分子量を有する直鎖状のコポリエステルのDynacoll(登録商標)7360をベースとするホットメルトを製造し、以下のものを添加した:
(A)2重量%の、本発明におけるプロセスによって製造されたビス[3−イソプロペニル−α,α−ジメチルベンジル]カルボジイミド、
(B)2重量%の、国際公開第A2005/111136号パンフレット記載のプロセスによって製造したビス[3−イソプロペニル−α,α−ジメチルベンジル]カルボジイミド。
これらの試験から、本発明によるカルボジイミドを使用しても、着色や発泡に関しては、目立った不都合な副次的作用はまったく生じないということが分かる。それとは対照的に、ホスホレンオキシドを用いた触媒作用での合成で製造し、トレース量の有機リン化合物まだ含んでいるカルボジイミドは、報告されたような着色および発泡の欠点を示している。
