Abstract EN
Carboxylated polystyrene (PS) microspheres were synthesized by the two-step dispersion polymerization of styrene in hydrocarbon alcohols (CnH2n+1OH, n=1–5) in the presence of acrylic acid (AA) as a functional comonomer, 2,2′-azobis-(2-methylbutyronitrile) (AMBN) as the initiator and polyvinylpyrrolidone (PVP55) as the dispersant.
The effects of solvent type, AA concentration, and first reaction time on the carboxyl content on the microsphere surfaces were investigated.
The PS microspheres were characterized by scanning electron microscopy, infrared spectroscopy, nuclear magnetic resonance, and gel permeation chromatography.
The results showed that the first reaction time of the two-stage dispersion polymerization had a great influence on the nucleation process, and appropriately prolonging the first-step reaction time had a great influence on the surface carboxyl content.
The effect of the solvent on the surface carboxyl content of PS microspheres was significant.
With n-butanol as the solvent, the carboxyl group content on the surface of the microspheres reached 57.05 mg/g.
