It is depicted a polymer composition with elastomeric properties at wide temperature ranges of the type comprising polymers and/copolymers resulting from substituted or unsubstituted vinyl aromatic monomers and from dienic monomers, which is homogeneous and compatible in nature, with such composition being based on stereoregular polymers and without requiring the additional use of compatibilizing agents. Likewise, it is depicted the process to obtain the same, as well as to hydrogenise them, without requiring the use of additional catalyzers or processes.
L'invention concerne une composition polymérique présentant des propriétés élastomériques lors de grands écarts de température, et contenant des polymères et/ou des copolymères dérivés de monomères vinylaromatiques substitués ou non substitués, et de monomères diéniques homogènes et compatibles, ladite composition étant basée sur des polymères stéréoréguliers sans nécessité d'utiliser des agents compatibles. L'invention concerne également un procédé d'obtention de ladite composition et d'hydrogénation de celle-ci, sans nécessité de procédés ou de catalyseurs supplémentaires.
