Definitions
- the field of the present invention is that of thermoplastic elastomeric copolymer (TPE) diene compositions comprising polyamides along its main chain.
- TPE thermoplastic elastomeric copolymer
- the present invention also relates to a process for producing a polydiene thermoplastic elastomer copolymer comprising polyamides along its main chain, and thus having improved mechanical and hysteretic properties. It relates more particularly to the rubber, tire and tread compositions of tires with low rolling resistance, comprising this thermoplastic elastomer.
- thermoplastic elastomer Materials with thermoplastic elastomer (TPE) properties combine the elastic properties of elastomers and the thermoplastic nature, ie the ability to soften and harden, reversibly, under the action of heat, pendent blocks.
- TPE thermoplastic elastomer
- a material with thermoplastic elastomer properties is sought, mainly based on polyamide, offering new properties. It is also desired a material that can be manufactured by a continuous, flexible, low cost and adaptable process for thermoplastic elastomers, thus polymers having high glass transition or melting temperatures, if any.
- Thermoplastic elastomers comprising polyamides at the end of the chain are known. However, these copolymers are unsatisfactory because they contain too little polyamide and their properties are different because of the end localization of the polyamide. In addition, because of the incompatibility of solvent between the elastomers and the polyamide, it is difficult to find a solvent common to these two compounds, which increases the difficulty of developing a synthesis process.
- thermoplastic elastomer (TPE) synthesis processes in order to overcome the disadvantages of known materials and processes and to allow a significant, or even quantitative, grafting of polyamides along the main chain.
- the object of the present invention is to overcome these drawbacks by proposing a method for synthesizing a thermoplastic elastomer comprising polyamides along its length. main chain, whose mass percentage of polyamide is between 10% and 35% by weight and thus having improved mechanical and hysteretic properties.
- the process according to the invention is a process for producing a polydiene-polyamide block thermoplastic elastomer copolymer (TPE) having a polyamide mass percentage of between 10% and 35% by weight, relative to the weight of the copolymer. comprising the reaction in an extruder of a polyamide, and a diene elastomer functionalized by at least one pendant epoxide function along the main chain.
- TPE polydiene-polyamide block thermoplastic elastomer copolymer
- the invention also relates to a thermoplastic elastomer copolymer (TPE) polydiene-polyamide block comb structure comprising units carrying a polyamide during the chain and linked to it via a group resulting from the reaction on an epoxide function of an amine function or carboxylic acid of the polyamide.
- TPE thermoplastic elastomer copolymer
- the polydiene-polyamide block TPE consists of a polydiene central block comprising one or more units carrying a polyamide block.
- the polyamide block is bonded to the unit of the central block via a group resulting from the reaction on a pendant epoxide functional group carried by the polydiene, an amine function or carboxylic acid of the polyamide.
- the invention also relates to a rubber composition comprising a TPE according to the invention.
- the invention also relates to a tread comprising the rubber composition according to the invention.
- the invention further relates to a tire comprising the rubber composition according to the invention, in particular in its tread.
- the process according to the invention makes it possible to obtain TPEs with improved mechanical and hysteretic properties making it possible to overcome the disadvantages of known materials and processes.
- a tread must offer the tire a very good level of road handling on a motor vehicle.
- This level of road behavior can be provided by the use in the tread of a suitably chosen rubber composition because of its rather high stiffness.
- a rubber composition for example it is known to increase the filler content or to reduce the level of plasticizer in the rubber composition or to introduce block copolymers of styrene and butadiene high styrene content in the rubber composition.
- some of these solutions generally have the drawback of increasing the hysteresis of the rubber composition.
- High hysteresis implies high rolling resistance, while low hysteresis means less rolling resistance.
- the hysteresis depends in particular on the viscosity and elasticity of the materials used in the tire. Hysteresis and therefore rolling resistance strongly influences fuel consumption.
- WO-2015/059271 a solution that increases the baking stiffness of a low hysteretic rubber composition by introducing a 1,3-dipolar compound into a filler-reinforced diene rubber composition.
