摘要：
Styrene-rich copolymer/ 2-hydroxyethyl acrylate rich copolymer [P(St-omega-HEA)] particles were prepared by emulsifier-free emulsion copolymerization of St with HEA. Fourier transform IR spectroscopy was used to follow the change of HEA content in the particles. The results of X-ray photoelectron spectroscopy measurements indicate that the HEA unit on the surface is richer than that inside the particles. Grafting of acrylamide (AAm) onto the surface of P(St-co-HEA) particles was carried out in an aqueous medium containing eerie ions. IR spectroscopy and laser light scattering were used to investigate the grafting polymerization. The morphologies of P(St-co-HEA) and P(St-co-HEA)AAm particles were observed using a transmission electron microscope. The amphiphilic properties of the particles were characterized by diesel oil and water.
