  • The extensive use of fossil fuels and the resulting threat of global warming have led to international treaties and to national legislation demanding emission reductions in greenhouse gases, particularly C02. The established legislation however, could not avoid a further drastic increase of the global carbon dioxide concentration. The increase is strongly correlated with the rising number of automobiles coming into service world-wide. Accordingly medium term, the contribution of the automotive and tire industries consists of an ongoing effort to reduce vehicle fuel consumption to eventually compensate for additional CO2 emissions derived from new vehicles. Improved tire rolling resistance contributes to fuel efficiency. Though significant rolling resistance reductions could be achieved through application of chain-end modified SSBR and neodymium based-polybutadiene, tire manufacturers search diligently for more energy efficient modified rubbers. In response to this, new technologies leading to multi-functionalized SSBR grades rather than SSBRls comprising only one filler active polar structural element are being developed. The new multi-functionalized TDAE oil-containing SSBR enables a significant improvement of the tire rolling resistance, as predicted by a 30 percent decrease of the measured tan 5 values at 60 0C. In addition, beneficial heat build-up and grip characteristics (measured as tan 5 at 0 and -10 0C) were found, together with balanced abrasion resistance properties. These benefits were found for both silica- and carbon black- containing compound vulcanizates, when compared with Styronfs commercialized modified SSBR grades as references.
