“…Further, no trace of bound rubber was found in the composite which was prepared from silicas with low number of N [N < 0.1 (nm −2 )]. High-resolution solid state nuclear magnetic resonance (NMR) results of silica filled polyisoprene composites reported by Ono et al 10 showed no direct chemical bonding between silanol groups and rubber molecules. These results suggest that the formation of bound rubber is closely related to the development of agglomerate of silica particles in the rubber matrix and that the formation mechanism of bound rubber in the silica filled rubber composite cannot be explained simply by the dispersive component of filler as suggested by Wolff and Wang.…”

“…According to the work of Kralevich and Koening49 van der Waals forces are responsible for the formation of the bound rubber in a nonpolar NR. Ono et al50, 51 also found no evidence for direct coupling between silanol groups and NR molecules at low processing temperature. Choi et al52 examined the SBR/silica interactions by microstructure analysis and revealed that the bound rubber is mainly formed by physisorption of the 1,2‐component of the butadiene units to the silica surface.…”

“…Silica filled vulcanizates also showed three T 2 Јs at 30°C, T 2L , T 2M and T 2S . Although the origin of T 2S has been discussed in some literatures [28][29][30] , the details are still uncertain. We reported that the content of filler-gel in silica filled vulcanizates prepared by mechanical mixing was very small 31,32) .…”
