Rheological properties of sulfur-containing hyperbranched polycarbosilanes and related magnetic compositions

详细

The rheological properties of hyperbranched polycarbosilanes with butyl and decyl terminal groups and their sulfur-containing analogs were compared. The use of various sulfurcontaining precursors made it possible to control both the total sulfur content and the position of sulfur atoms in the molecular structure. The magnetic compositions based on sulfur-containing hyperbranched polycarbosilanes were prepared for the first time, and the influence of the external magnetic field intensity on their rheological properties was studied. The introduction of the sulfur atom improves the stability of the magnetic composition, while their magnetorheological response remains unchanged.
