FIELD: chemistry of polymers, chemical technology.

SUBSTANCE: invention relates to a method for preparing thermoelastomers based on polyolefins and triple ethylenepropylene-diene rubber. The composition is prepared by the complete dynamic vulcanization of mixture of the following components, mas. p. p.: TSEPDR, 100.0; polypropylene, 25-60; low density polyethylene, 1-10; oil, 20-100; sulfur-accelerating vulcanization comprising the following components: sulfur, 0.1-2.0; thiuram, 0.1-1.5; Altax, 0.1-0.5; stearic acid, 0.1-20.0; zinc oxide, 0.5-8.0, or peroxide vulcanization comprising the following components: dicumene peroxide, 0.1-2.0; bis-maleimide, 0.1-2.5; novolacs alkylphenolformaldehyde resin, 0.2-10.0; organic phosphite, 0.02-1.0; pigment, 0.01-2.0; filling agent, 0.1-50.0; antioxidant, 0.1-2.0, and phthalate plasticizers, 0.5-10.0. The content of oil, polyethylene, phthalate plasticizers, novolacs resin and polypropylene is bound by the ratio. Invention provides enhancing thermostability, resistance against multiple temperature effects during the technological processing, resistance against harmful catalytic effect of metal with transient valence and improving the ecology of the process. Invention can be used in making elastic, atmosphere-resistant materials used in building industry, cable, automobile and light industries and in manufacturing different goods for consumption.

EFFECT: improved preparing method, valuable technical properties of composition.
