- Abstract
Porous, hydroxy functionalized, polymer particles, having BET surface areas up to 146 m²/g, were synthesized by suspension polymerization of water in oil (w/o) emulsions. The emulsions were prepared by mixing polyoxyethylene sorbitan monooleate (Tween-80) solutions in water with a mixture of 2-hydroxyethyl methacrylate (HEMA), styrene (S) and divinylbenzene (DVB) dissolved in a mixture of cyclohexanol (CyOH) and octanol (OctOH). The resulting polymer particles were characterized by optical microscopy, scanning electron microscopy, infrared spectroscopy, and thermal gravimetric analysis. Nitrogen adsorption/desorption isotherms and particle size distribution were also determined. The influence of the organic porogen nature and the concentrations of divinylbenzene and Tween-80, the fraction of water in the w/o emulsions and the agitator rotation on the properties of the provided polymer particles were analyzed and discussed.
