Multiple and diverse applications have been recently found for miniemulsions and miniemulsion polymerization. In this work, miniemulsion polymerization is presented as a suitable technique for the preparation of high-solid-content latices with large particle sizes. Monomer miniemulsions were prepared with a high-pressure homogenizer, and droplet sizes of 200-700 nm were obtained. Latexes with particle sizes larger than the sizes commonly accepted for miniemulsion polymerization were obtained. With fixed operational conditions of the homogenizer, the type of stabilizer was the key parameter determining the droplet size and the droplet size distribution. The particle size of the latices obtained by miniemulsion polymerization indicated that the particles were mainly formed by droplet nucleation. Latexes obtained by this process have multiple applications, including use as seeds in the polymerization of high-solid-content latices. This article shows that potential new applications for miniemulsion polymerization are far from being exhausted. (C) 2004 Wiley Periodicals, Inc.
