Embodiment

[0120] The purpose of this example is to compare the processing and dynamic properties of different rubber compositions, as well as to compare the tire performance of treads obtained from these rubber compositions.

[0121] Composition A0 is a control composition.

[0122] Compositions A2 and A5 are comparative compositions.

[0123] Compositions A1, A3, A4, A6 and A7 are compositions according to the invention.

[0124] Compositions A0, A2 and A5 contain 85 phr of standard SBR and vary in carbon black content and fineness:

[0125] -A0 contains 56.5phr of N234 (CTAB specific surface area = 120m 2 / g)

[0126] -A2 contains 56.5phr of N134 (CTAB specific surface area = 135m 2 / g)

[0127] -A5 contains 54phr of CRX1346 (CTAB specific surface area = 160m 2 / g)

[0128] Compositions A1, A3 and A6 contain 85 phr of SBR according to the invention with a low polydispersity index and differ in carbon black content and fineness:

[0129] -A1 contains 56.5phr of N234 (CTAB speci...

Abstract

The invention relates to a rubber composition based on one or more specific functionalized diene elastomers and one or more carbon blacks with a CTAB specific surface area varying between 100 and 200 m<2> / g.

Description

technical field [0001] The present invention relates to a rubber composition based on one or more functionalized diene elastomers and one or more carbon blacks having a specific CTAB specific surface area, and to a semi-finished product comprising said rubber composition and Incorporate this semi-finished tire. Background technique [0002] Since the need to save fuel and protect the environment has become a priority, it is desirable to prepare mixtures with good wear properties and at the same time as low a hysteresis as possible, so that they can be processed into the form of rubber compositions, said The rubber composition can be used in the manufacture of various semi-finished products that participate in the composition of the tire casing such as, for example, the undertread, sidewalls or treads, in order to obtain tires with improved wear resistance without impairing rolling resistance. Safety during braking on wet surfaces is also a consequence that must be maintaine...
