Abstract
Nanocomposites include metal oxide nanoparticles and (meth)acrylic acid polymers where the nanoparticles are surface modified with a carboxylic acid silane and where the (meth)acrylic acid polymer is at least partially neutralized. The compositions are transparent, with high transmission and low haze up to very high nanoparticle loading. The compositions also exhibit improved mechanical properties of impact resistance and tensile modulus.
