We investigate the miscibility of acrylic polyhedral oligomeric silsesquioxanes (POSS) [characteristic size dz2 nm] and poly(methyl methacrylate)(PMMA) in order to determine the effect of well-dispersed POSS nanoparticles on the thermomechanical properties of PMMA. Two different acrylic POSS species (unmodified and hydrogenated) were blended separately with PMMA at volume fractions up to fZ0.30. Both POSS species have a plasticizing effect on PMMA by lowering the glass transition temperature Tg… CONTINUE READING
