- Compositions C2 and C3 comprise the same number of moles of grafted compounds A or B, namely 0.2 mole%.
- TESPT (marketed by Evonik under the reference “S 169”;
- Fes compositions are prepared as follows: one introduced into an internal mixer “Polylab” of 85 cm3, filled to 70% and of which the initial temperature of the tank is approximately 1 10 ° C, the diene elastomer.
- compound A or compound B is introduced at the same time as the diene elastomer.
- a thermomechanical work of a minute and a half is carried out at a temperature of 120 ° C.
- one or more reinforcing fillers are introduced, the agent for coupling the filler with the diene elastomer and then, after one to two minutes of mixing, the various other ingredients with the exception of the system. vulcanization.
- Thermomechanical work is then carried out (non-productive phase) in one step (total mixing time equal to approximately 5 minutes), until a maximum “fall” temperature of 160 ° C. is reached.
- the mixture thus obtained is recovered, it is cooled and then the vulcanization system (sulfur and sulfenamide type accelerator) is added on an external mixer (homo-finisher) at 25 ° C, while mixing everything (productive phase) for approximately 5 to 6 minutes.
- vulcanization system sulfur and sulfenamide type accelerator
- compositions thus obtained are then calendered in the form of plates (thickness of 2 to 3 mm) or of thin rubber sheets for the measurement of their physical or mechanical properties. 2) Characterization tests - Results
- composition C2 comprising the comparative compound, which comprises an elastomer modified with a compound comprising an unsubstituted imidazolidinone function, exhibits a decrease in hysteresis (tan (ô) max at 23 ° C), relative to composition C1 which does not include a modified elastomer.
- composition C3 comprising the compound according to the invention, which comprises an elastomer modified with a compound comprising an N-substituted imidazolidinone function, exhibits a significant decrease in hysteresis compared with comparative composition C 1 as well as a significant decrease in hysteresis compared to comparative composition C2, which already exhibited good hysteretic properties compared to composition C1.
- the elastomer modified by the compound according to the invention therefore makes it possible to improve the hysteresis of the compositions containing it, and therefore to improve the rolling resistance performance of the compositions containing it.
