Embodiment Construction

[0012] I.

[0013] In this specification, unless otherwise specified, all percentages (%) shown are percentages by weight.

[0014] Furthermore, the term “phr” (pce in French) within the meaning of this patent application means parts by weight per 100 parts by weight of elastomer. Within the meaning of the present invention, thermoplastic elastomers (TPE) are included in elastomers.

[0015] In addition, any numerical interval represented by the expression "between a and b" represents a numerical range from greater than a to less than b (that is, excluding the end values ​​a and b), while any numerical value represented by the expression "a to b" Interval means a numerical range extending from a to b (ie including the strict endpoints a and b).

[0016] I-1. Composition of the tread

[0017] The tire according to the invention is provided with a tread having the essential features based on at least one thermoplastic elastomer as main elastomer, said thermoplastic elastomer...

Abstract

The present invention relates to a pneumatic tire provided with a tread such that said tread comprises at least one thermoplastic elastomer, being a block comprising at least one elastomeric block and at least one thermoplastic block, and hollow particles segment copolymers.

Description

technical field [0001] The present invention relates to treads for tires, and to elastomeric compositions used in the manufacture of such treads. Background technique [0002] In conventional tires, the tread is mainly based on diene elastomers. [0003] A continuing goal of tire manufacturers is to improve the grip of tires on the ground while maintaining a very good level of road handling with respect to motor vehicles. [0004] For improved road handling, greater tread stiffness is desirable. However, this stiffness of the tread (at least that part of the surface that is in contact with the ground during the running of the tyre) destroys in a known manner the dry grip properties, but also on wet, snowy or frozen ground . [0005] There is thus a compromise in performance to be optimized. [0006] For this purpose, document WO 02 / 10269 provides specific formulations for treads based on diene elastomers and on reinforcing inorganic fillers with coupling agents and compr...
