Abstract
Poly (methyl methacrylate-co-butyl acrylate) as shell and vinyl silica nano-particles as core were prepared by in situ seed emulsion polymerization. The monomer concentration ratio of butyl acrylate (BuA), and methyl methacrylate (MMA) was changed. The ratio of the monomers MMA/BuA were 60/40, 70/30, 40/60 and 30/70 at constant dose of vinyl silica nano-particles 5% (based on total monomer ratio). The prepared nano emulsions were characterized using thermal analyses, HRTEM, FTIR and Zeta potential. The results have shown that monomer concentration ratio had a significant influence on glass transition temperature (Tg). Thermo gravimetric analysis showed that the systems with higher BuA fraction had better thermal stability than systems with higher (MMA) fraction.
