Definitions
- the field of the present invention is that of modifiers intended to functionalize unsaturated polymers, that is to say polymers carrying unsaturated carbon-carbon bonds in their chains. More specifically, these modifying agents are 1,3-dipolar compounds.
- the invention also relates to a process for the synthesis of these compounds and their synthesis intermediates.
- Modification of the structure of a polymer is particularly desirable when it is desired to bring together a polymer and a filler to form a composition.
- This modification can make it possible to improve, for example, the dispersion of the filler in a polymer matrix and thus make it possible to obtain a more homogeneous material and ultimately to improve the properties of the composition.
- the modification of the structure of the polymers can in particular be carried out by means of functionalizing agents (or modifying agents), coupling or starring or post-polymerization, in particular with the aim of obtaining a good interaction between the polymer thus modified. and the filler, whether carbon black or a reinforcing inorganic filler.
- WO2019102132A1 is known, as a functionalizing agent, an aromatic nitrile oxide compound comprising an epoxy ring, the epoxy ring being connected to the aromatic ring carrying the nitrile oxide by a divalent group -OCH2-.
- This functionalizing agent, 2- (glycidyloxy) -1-naphtonitrile oxide once grafted onto a copolymer of styrene and butadiene makes it possible to improve the reinforcement index of a composition containing such a modified copolymer and to reduce Significantly the non-linearity of this composition with respect to a composition comprising a copolymer of unmodified styrene and butadiene.
- the improvement in the reinforcement and the nonlinear behavior of this composition are obtained by maintaining the hysteresis properties at a level almost identical to that of a composition comprising an unmodified styrene-butadiene copolymer.
- modified polymers in particular elastomers, in particular modified diene elastomers, which make it possible to obtain compositions having improved hysteresis properties compared to the compositions of the prior art.

- An aim of the present invention is therefore to provide new polymer modifying agents which, once grafted to these polymers, make it possible to obtain compositions exhibiting an improvement in the reinforcement index and an improvement in the hysteresis properties without decrease in stiffness properties when cooked.
- an aromatic nitrile oxide having an epoxy ring linked to the aromatic group carrying the nitrile oxide by a specific -O-alkanediyl group of a specific length, once grafted onto an elastomer comprising unsaturated carbon-carbon bonds made it possible to obtain compositions simultaneously exhibiting an improvement in the reinforcement index and an improvement in the hysteresis properties.
