Elastomer-filler composite materials are technically very important and widely used. In particular, the reinforcing effect achieved by the addition of carbon black or silica fillers to a polymer matrix is commonly used to tune macroscopic properties. In contrast to that, plasticizer effects were found recently by adding very small particles. Though its technical significance both effects have not been understood in detail at the microscopic level.

We present recent results of Small Angle Neutron Scattering measurements on the chain conformation of polyethylene-propylene in the presence of nanoparticles (polyhedral oligomeric silsesquioxane) at different temperatures and various filler loadings.
