CORRELATION LENGTH OF CONCENTRATION FLUCTUATIONS IN DYNAMICALLY ASYMMETRIC MIXTURES OF INDUSTRIAL INTEREST

Self-concentration and concentration fluctuations are the two ingredients giving rise to the peculiar phenomenology observed for mixtures with dynamic asymmetry, as they are SBR/additive systems of interest in the tire industry. With SANS experiments on samples where SBR is deuterated we want to determine the correlation length of the concentration fluctuations in SBR/additive mixtures as function of the dynamic assymetry and the properties of the additive and look for a possible correlation with the self-concentration.
