Morphology and rheological behaviour of maltenes/polymers and asfalts/polymers blends with ramified partially hydrogenated type polymers

Abstract : A study of maltenes/polymer and asphalt/polymer blends, with two styrene-butadiene-styrene (SBS) polymers with four-branch star-like chain architecture is reported in this work. The employed polymers, with the same overall composition and distribution, were in-situ partially hydrogenated using a Nickel II Ziegler-Natta type catalyst without cross-linking or chain scission reactions. Blends were prepared by a melt mixing procedure and studied by fluorescence microscopy and rheological measurements. Results indicate that maltene/polymers blends are bi-phase heterogeneous systems with swollen polymer-rich and maltenes-rich phases, while asphalt/polymers blends are tri-phase systems with swollen polymer-rich, maltenes-rich and stabilized asphaltenes phases. In both cases, the rheological behavior of blends is mainly affected by the swollen polymer rich phase. It was confirmed that the rheological properties of PMM depend on the molecular characteristics of the copolymer such as the total molecular weight and molecular architecture, which determine the material behavior
