FIELD: chemistry.
SUBSTANCE: peroxide-cured thermoplastic vulcanisate contains thermoplastic and a non-halogenated elastomer. The thermoplastic is selected from a group comprising polypropylene, polyethylene, polystyrene, a copolymer of acrylonitrile, butadiene and styrene, allyl resins, a copolymer of ethylene and vinyl alcohol, fluoroplastic, polyacetals, polyacrylates, polyacrylonitriles, polyamides, polyimides, polycarbonates, polyesters, polethylene oxide, polypropylene oxide, polyethylene glycol, polypropylene glycol, polyvinylidene chloride and mixtures thereof. The non-halogenated elastomer contains repeating units obtained from isobutene and 3.5 mol % repeating units obtained from isoprene.
EFFECT: disclosed thermoplastic vulcanisates can be used when producing moulded articles for applications which require high degree of purity, reduced hygroscopicity and preventing decolouration of the article.
