Abstract
Description
重合度=(開始時NCO−完了時NCO)/開始時NCO×100
に従って計算することができる。
本発明を、以下の例を用いてより詳細に説明する。
全てのパーセンテージは、特段の記載がない限り、重量に対するものである。
リン酸ジブチル(Sigma Aldrich)
2−エチルヘキサン−1−オール(Sigma Aldrich)
N,N,N−トリメチル−N−ベンジルアンモニウムヒドロキシド(メタノール中40%溶液)(Sigma Aldrich)。
酢酸ブチル(Azelis Deutschland GmbH、ザンクト・アウグスティン)。
撹拌機、還流冷却器、N2用導管および内部温度計を備えた四ツ口フラスコに、1092g(6.49mol)のヘキサメチレン−1,6−ジイソシアネート(HDI)を装入し、室温で3回脱ガスし、そして窒素を供給した。そのバッチを、引き続き60℃に加熱し、6.0mlの触媒溶液(メタノールおよび2−エチルヘキサノール中のN,N,N−トリメチル−N−ベンジルアンモニウムヒドロキシドの1.5%溶液)を、発熱的三量体化が60℃〜80℃の温度で維持される速度で計量供給した。NCO含量40.8重量%に達したら、リン酸ジブチル(使用されたトリメチルベンジルアンモニウムヒドロキシドに対する等モル量)で反応を停止させ、そして過剰のPDIを、140℃および0.5mbar〜0.6mbarの圧力での薄膜蒸留によって除去した。
撹拌機、還流冷却器、N2用導管および内部温度計を備えた四ツ口フラスコに、1000g(6.49mol)のペンタメチレン−1,5−ジイソシアネート(PDI)を装入し、室温で3回脱ガスし、そして窒素を供給した。そのバッチを、引き続き60℃に加熱し、9.0mlの触媒溶液(メタノールおよび2−エチルヘキサノール中のN,N,N−トリメチル−N−ベンジルアンモニウムヒドロキシドの1.5%溶液)を、発熱的三量体化が60℃〜80℃の温度で維持される速度で計量供給した。NCO含量36.7%に達したら、リン酸ジブチル(使用されたトリメチルベンジルアンモニウムヒドロキシドに対する等モル量)で反応を停止させ、そして過剰のPDIを、140℃および0.5mbar〜0.6mbarの圧力での薄膜蒸留によって除去した。
図1は、2種のポリイソシアネート混合物A(比較例、実線)およびB(本発明の例、点線)のいわゆる希釈系列を示している。この場合に、固体含量を減少させている複数の溶液(有機溶剤として酢酸ブチル)を、それぞれのポリイソシアネート混合物から調製し、引き続き念入りに混合した後に、粘度を、AntonPaar社製のMCR301レオメーターを使用してカップ/ローターシステム(CC27)中で調査する。
表1において、配合物1〜4は、2種のポリイソシアネートA(比較例)およびB(本発明の例)ならびにNuplex Resins GmbH(ビターフェルト)社製の2種の異なるポリアクリレートを用いてNCO/OH比1.0で調製し、そしてDIN4カップ中での流下時間20秒を、酢酸ブチルによる希釈によって調節した。測定された固体含量から明らかなように、比較のための配合物1および2ならびにまた配合物3および4のそれぞれの吹き付け粘度に関与している固体含量は、同一水準にある。
