High vinyl high styrene solution SBR

Hybrid factors influencing wet grip and rolling resistance properties of solution styrene‐butadiene rubber composites

“…The T g values obtained from the DMA results are listed in Table . The T g of an SBR usually tends to increase as the styrene content increases and the 1,2‐unit content decreases . T g values of the SBR composites obtained from the DMA results on the whole tended to increase with styrene content but the correlation is low (Table ).…”

“…The T g of an SBR usually tends to increase as the styrene content increases and the 1,2-unit content decreases. 9 T g values of the SBR composites obtained from the DMA results on the whole tended to increase with styrene content but the correlation is low ( Table 4). The T g values of the OE-SSBR samples were relatively lower than those of the non-OE-SSBR samples when considering the styrene content.…”

“…Halasa et al studied the properties of solution SBR compounds with various microstructures and reported that solution SBRs with high vinyl contents had good characteristics in traction and fuel economy. 9 In addition to the microstructures of SBR, the modification of SBR, filler types and the modification of silica also influence the properties of SBR compounds. [10][11][12][13][14][15] Dynamic mechanical analysis (DMA) evaluates dynamic physical properties of a rubber composite, and is often used to predict the wet grip and rolling resistance properties.…”

Unusual Reactivity Patterns of 1,3,6,8-Tetraazatricyclo-[4.4.1.13,8]-dodecane (TATD) Towards Some Reducing Agents: Synthesis of TMEDA

“…Many of these complexes have shown catalytic activity in oxidative coupling reactions [8], olefin polymerizations [9], oxidative carbonylation of phenol to produce diphenyl carbonate (DPC) [10], and alkyl-alkyl cross-coupling reactions [11]. In the same way, TMEDA has been used as an initiator of anionic polymerization in the synthesis of high vinyl copolymers containing styrene and butadiene [12], lithiation by alkylLi/TMEDA [13], reductive ring opening of many oxygen-, nitrogen-, or sulfur-containing heterocycles [14], synthesis of asymmetric hydroborating reagents [15] and diastereoselective dihydroxylation of olefins [16]. Although some methods for obtaining 6 are known [17], many of them suffer from limitations of starting material availability.…”

Preparation, structure, and properties of end‐functionalized miktoarms star‐shaped polybutadiene–sn–poly(styrene–butadiene) rubber

“…Therefore, reducing the tire tread rolling resistance is one of the effective steps to save energy. Nowadays, a lot of studies have been focused on the development of energy‐saving green tire tread materials by macromolecule design …”
