Popis: Scaling of dynamic shear and calorimetric data in a series of commercial statistical styrene (23% weight)-butadiene emulsion copolymerisates (SBR) vulcanisates with several neutral-filler contents and filler diameters against an effective filler diameter (filler and interfacial) allows the determination of the length of immobilized modes in the interfacial region. These mode lengths are compared with the bulk characteristic length of glass transition and network lengths in the SBR matrix. A dispersion law (mode length vs. mode frequency) in the shear relaxation zone between main transition and network-rubbery plateau zone could be determined for the first time (exponent −12.5±3).
