Abstract
【解決手段】スチームまたは不活性ガスを使用して分散体をストリッピングすることを要件とする、ポリマー分散体の殺生物剤化合物を安定化させる方法。
【選択図】なし
Description
水性ポリマー分散体とスチーム(steam)とを提供することと;
水性ポリマー分散体とスチームとをストリッパー中で接触させることと;
スチームを水性ポリマー分散体から分離することとを含み;
水性ポリマー分散体とスチームとをストリッパー中で接触させた後に少なくとも1種類の殺生物剤が加えられる、方法が提供される。
熱安定化試験
28グラムの分散体試料を50℃のオーブン中に入れる。7日後、1グラムの試料を有効成分分析のために取り出して、後述の方法で測定する。14日後、さらに1グラムの試料を分析する。この材料中のイソチアゾロン化合物レベルを後述の方法によって測定する。これらの結果を、ゼロ時間の対照と比較する。この対照は、オーブン中に入れなかった試料である。この対照は、入手してすぐに分析する。
9部の水対1部の分散体の比率で分散体試料を脱イオン水で希釈する。試料を混合して、イソチアゾロンを水(水性)相中に抽出する。試料を遠心分離して、透明な液相を抜き取る。この透明な液体をHPLC試験機、たとえばアジレント1100シリーズ(Agilent 1100 Series)に注入して、イソチアゾロンレベルを測定する。
ポリマー分散体を、5ガロンのバッチ式反応器中で調製した。この分散体は、アクリル酸ブチル/スチレンの水性分散体であった。この分散体ポリマーを界面活性剤およびアクリル酸モノマーによって安定化させた。得られた分散体の固形分は53〜54重量%であった。この分散体の最終pHは6.8〜7.8の間であり、粘度は200cp未満であった。
部分1.バッチ重合後にイソチアゾロンを加えた。
部分2.バッチ重合の2時間後にイソチアゾロンを加えた。
部分3.バッチ完了後にイソチアゾロンを加え、続いてその分散体試料のスチームストリッピングを行った。
部分4.試料のスチームストリッピングを行い、続いてイソチアゾロンを加えた。
