METHOD OF PRODUCING THERMOPLASTIC ELASTOMER COMPOSITION Russian patent published in 2013 - IPC C08J3/24 C08L23/06 C08L23/34 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a thermoplastic elastomer composition based on polyethylene and chlorosulphonated polyethylene for making various elastic industrial rubber articles by extrusion, pressure moulding and blow moulding. The method is realised by dynamic mixing of polyethylene with chlorosulphonated polyethylene in the presence of a vulcanising system which contains magnesium oxide, a mixture of organic acids and a mixture of sulphur vulcanisation accelerators of a group of thiazoles. At the step of dynamic mixing of polymers, magnesium oxide is added first, followed addition of a mixture of organic acids in a combination with a mixture of sulphur vulcanisation accelerators to carry out dynamic vulcanisation.

EFFECT: composition obtained using the invention has high resistance to aggressive media, oil and petrol resistance and frost resistance, while maintaining resistance to ozone and the atmosphere.
