POLYMERIC COMPOSITION HAVING ELASTOMERIC PROPERTIES OVER WIDE TEMPERATURE RANGES, AND PREPARATION METHOD THEREOF

摘要

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.
