Sub-Product

Solution-SBR (S-SBR) is produced by an Anionic Polymerization Process. Polymerization is initiated by Alkyl Lithium Compounds. Water and Oxygen are strictly excluded. The Process is homogeneous (all Components are dissolved), which provides greater control over the process, allowing tailoring of the Polymer. The Organolithium Compound adds to one of the Monomers, generating a Carbanion that then adds to another Monomer, and so on. For Tire manufacture, S-SBR is increasingly favored because it offers improved wet grip and reduced rolling resistance, which translate to greater safety and better Fuel economy, respectively.
