CONCENTRATION FLUCTUATIONS AND BROADENING OF THE DYNAMICAL RESPONSE IN DYNAMICALLY ASYMMETRIC MIXTURES OF INDUSTRIAL INTEREST
Relating the dynamic response in dynamically asymmetric mixtures with concentration fluctuations is a fundamental issue, but can also be of utmost interest to elaborate predictive models for the behavior of the materials involved in the rubber industry. In a previous work on blends of SBR with PS we have found that the size of the relevant region for the dielectric response, Rc, turns to be practically independent of temperature and composition, always of about 1nm. We want to check the universality of this important result by varying the properties of the high-Tg component (PS) of the mixture, in particular, changing its molecular weight. To do this we need to characterize by SANS the concentration fluctuations of the system and their temperature dependence.
