SEM images of unmodified (U30) and TESPT‐grafted (U30‐SCA) silica compounds show that pre‐grafting eliminates agglomerates. Stress relaxation data fitted with a constrained five‐element Weichert model give discrete relaxation times (τ1$$ {\tau}_1 $$‐τ5$$ {\tau}_5 $$), both reduced by grafting. Their ratio, the Filler Network Index (FNI = τ1$$ {\tau}_1 $

Emerging Directions in Emulsion Styrene‐Butadiene Rubber: Molecular Design, Filler Interfaces, and Sustainable Feedstocks. ABSTRACT Emulsion styrene butadiene rubber (eSBR) is often viewed as a mature elastomer platform whose role in high‐performance tire applications is increasingly challenged by solution SBR (sSBR), particularly in silica‐filled ...

Sulfur-Induced cis-trans Isomerization of Polybutadiene
Both high cis-1,4-polybutadiene and high trans-1,4-polybutadiene were found to isomerize when heated in the presence of elemental sulfur. The kinetics of the sulfur induced isomerization of high cis-1,4-polybutadiene were studied over a wide range of ...

"Synthesis and characterization of high vinyl star-shaped liquid polybutadiene"
Using cyclohexane and n-hexane as solvents, butadiene as monomer, and n-butyllithium as initiator, star-shaped liquid polybutadiene was synthesized via arm-first method with di-tetrahydrofurfuryl propane (DTHFP) as structure regulator.

Synthesis and characterization of conducting polypyrrole-cis-1,4-polybutadiene composites
Conducting composite films of cis-1,4-polybutadiene with polypyrrole were prepared electrochemically. Polymerization of pyrrole was carried on cis-1,4-polybutadiene-coated platinum electrodes.

Polybutadiene and a copolymer consisting of 76.5 per cent butadiene and 23.5 per cent of styrene were investigated as to the rate of their thermal degradation. The rates for polybutadiene indicated an activation energy of 62 kilocalories per mole.
