FIELD: chemistry.SUBSTANCE: invention refers to an elastomeric thermoplastic composition having a compression resistance at a temperature of 20°C to 100°C containing hydrated styrene-butadiene thermoplastics. The thermoplastics forming the above composition are linear or radical, are characterised by the vinyl content of 35.8 to 60 wt %, the styrene content of 30 to 41 wt %, a molecular weight of 200,000 to 600,000 and the Brookfield viscosity at 5 wt % in cyclohexane of less than 300 cP. What is also described is a method for producing the composition, the product prepared by pressure casting or extrusion of the composition.EFFECT: good processibility, adequate compressive strength of the non-vulcanised and vulcanised compositions.33 cl, 4 tbl, 4 ex |
