Polymer composition with elastomeric properties at wide temperature ranges and process for the preparation thereof

摘要

The invention relates to a polymeric composition having elastomeric properties over wide temperature ranges, of the type that comprises polymers and/of copolymers which are derived from substituted or non-substituted vinylaromatic monomers and compatible, homogeneous diene monomers. The inventive composition is based on stereoregular polymers and does not require the use of compatibilizer agents. The invention further relates to the method of obtaining said compositions and of hydrogenating same without the need for additional catalysts or methods.
