プレポリマーが下記のように調製される:既知量のポリオールを500mlのガラス製ジャーに仕込み、続いて、ジャーを70℃に加熱する。ポリエーテルポリオールのこの混合物に、同様に70℃に加熱されるIPDIを加える。約80ppmの量のベンゾイルクロリドを加えて、ポリオールにおける残留塩基を中和する。混合物を窒素雰囲気下で撹拌し、85℃のオーブンに入れる。オーブンに半時間入れた後、プレポリマーを再び混合し、その後、オーブンに一晩放置して、反応させ、取り出し、その後、室温に冷却する。
分散物が、高剪断ミキサーを3000rpmで使用して、3部(乾燥基準で100部のプレポリマーに対して)のラウリル硫酸ナトリウム界面活性剤を14wt%の濃度でプレポリマーに加えることによって調製される。さらに水が、相反転が認められるまで加えられる。その後、鎖延長剤のエチレンジアミンが、所望される最終濃度に達するためのさらなる水とともに分散物に加えられる。
