多孔聚合物膜已从聚（甲基丙烯酸丁酯）胶乳颗粒与表面磺酸盐基团制备，并已被证明保留高达90%的原始胶乳颗粒的催化能力。胶乳膜作为反应性表面优于胶乳颗粒的优点包括更容易从反应介质中除去和更容易清洁/更新聚合物膜。薄膜的特征在于比表面积，压汞法，电导滴定。评价了甲酸乙酯酸催化水解的反应活性。
Porous polymer films have been prepared from poly(butyl methacrylate) latex particles with surface sulfonate groups and been shown to retain up to 90% of the catalytic capacity of the original latex particles. Advantages of latex films over latex particles as reactive surfaces include easier removal from the reaction medium and easier cleaning/rejuvenation of the polymer films. The films have been characterized by specific surface area, mercury porosimetry, and conductometric titration. Reactivity was evaluated for the acid-catalyzed hydrolysis of ethyl methanoate.
