[00130]本発明を多数の実施例でさらに説明するが、それらは本発明の範囲を制限するものと見なすべきではない。それらの実施例に挙げられている成分は、以下のような商品名を持ち、列挙されている供給元から入手可能であり、示されている化学組成を有する。
上式において、RLは液体試料の面積比であり、RFは硬化1次の面積比である。
光ファイバー上の2次コーティングの硬化度は、ダイヤモンドATR付属装置を用いてFTIRで求める。FTIR装置パラメーターには次のものが含まれる:100の同時追加スキャン、4cm−1の解像度、DTGS検出器、スペクトル範囲4000〜650cm−1、および信号対雑音を向上させるための省略時ミラー速度におけるおよそ25%の減少。2つのスペクトルが必要とされ、それはファイバー上のコーティングに対応する未硬化液体コーティングのスペクトルとファイバー上の外側コーティングのスペクトルである。液体コーティングのスペクトルは、ダイヤモンド表面をコーティングで完全に覆った後に得る。可能であれば、液体はファイバーを被覆するのに用いるのと同じバッチのものにすべきであるが、最低限の要件として、それは同じ配合物でなければならない。スペクトルの最終形式は吸光度にすべきである。
上式において、RLは液体試料の面積比であり、RFは硬化2次コーティングの面積比である。
