摘要：

Recently, we reported that multi-hollow polymer microspheres can be produced by a two-step treatment of submicron-size styrene-butyl acrylate-methacrylic acid (74.3/17.0/8.7, molar ratio) terpolymer emulsion particles with alkali and acid. In this article, the effects of initial pH value, temperature and time in the process of alkali treatment - the first step in the formation of the multi-hollow structure within the particles - are examined in detail.
