“…Polymer microspheres are new functional materials with some specific properties. Preparation and application of polymer microspheres have become an important research field in polymer science and have attracted the attentions of many researchers (Erdem and Bicak, 2016; Wei et al., 2016; Zhang et al., 2016) At present, primary methods of preparing polymer microspheres are suspension polymerization (Liu et al., 2016; Yu et al., 2014; Xie et al., 2017), emulsion polymerization (Fan et al., 2016; Yang et al., 2015; Zhang et al., 2012), dispersion polymerization (Beal et al., 2016; Zhang et al., 2011), and seed swelling polymerization (Srisopa, 2016; Xu et al., 2010). Dispersion polymerization is a relative new method for the preparation of monodispersed polymer microspheres with particle size ranging from 0.5 to 8.0 μm.…”

Carboxyl-functionalized polymer microspheres with a rosin moiety were prepared through dispersion polymerization using styrene, disproportionated rosin ester, and methylacrylic acid as raw materials. The effects of dispersion medium (ethanol/water) ratio, monomer mass proportion and initiator concentration on the polymer microspheres were studied. Scanning electron microscopy, laser particle size analysis, thermogravimetric analysis and Fourier transform infrared spectroscopy were used to characterize the microspheres, and their carboxyl contents were determined by the conductance titration method. The adsorption of methylene blue of the microspheres was also investigated. The results showed that rosin-based carboxyl-functionalized polymer microspheres were successfully synthesized. The microspheres exhibited smooth, spherical shapes with good monodispersity and high thermal stability. The carboxyl content of the microspheres prepared under optimum conditions was 0.089 mmolÁg À1 , with the average particle size approximately 950 nm. With increasing carboxyl contents of the polymer microspheres, their methylene blue adsorption capacities increased. The maximum methylene blue adsorption capacity of the microspheres was 59.55 mgÁg À1 in the highest carboxyl content.
