Crosslink Effects of Octavinyl Polyhedral Oligomeric Silsesquioxane on the Mechanical and Thermal Properties of Polyacrylate Nanocomposites

Article Preview

Abstract:

Poly(butyl acrylate-co-methyl methacrylate-co-octavinyl polyhedral oligomeric silsesquioxane) (OVPOSS-P(BA-MMA)) nanocomposites were synthesized by emulsion polymerization. The structures of nanocomposites were characterized by Fourier transform infrared spectrum (FTIR) and solubility experiment. It was shown that the network structures have been formed during the copolymerization. Dynamic mechanical analysis (DMA) was used to investigate the dynamic mechanical and thermal properties. The data indicate that the crosslinking density apparently affects the mechanical and thermal properties of OVPOSS-P(BA-MMA).
