Toward theta-shaped polymer composite particles by seeded emulsion polymerization

Key Points

• The aim is to synthesize theta-shaped polystyrene-poly(glycidyl methacrylate) composite particles through seeded emulsion polymerization.
• Seeded emulsion polymerization was employed using polystyrene seed particles.
• Seed particles were pre swollen with dibutyl phthalate and glycidyl methacrylate.
• The synthesis conditions and their effects on particle formation were analyzed.
• Successfully synthesized theta-shaped (two-lobed) composite particles.
• The design affects the structural characteristics of the composite particles.
