（图所示）通过使用温度敏感的聚合物载体聚（n -烷基丙烯酰胺），证明了在水介质中催化反应的新概念，聚（n -烷基丙烯酰胺）通过与磷钨酸组装转化为催化剂。在高温下，由于形成乳剂，催化剂在乙醇与h2o2氧化中的活性很高，而在低温下，产物和催化剂很容易分离（见图）。
(Figure Presented) A new concept for catalytic reactions in aqueous media is demonstrated by using a temperature-responsive polymer support, poly (N-alkylacrylamide), which is converted into a catalyst by assembly with phosphotungstic acid. At high temperature, the catalyst is highly active in the oxidation of alcohols with H 2 O 2 owing to the formation of emulsions, whereas the product and catalyst are easily separated at low temperature (see scheme).
