METHOD OF OBTAINING THERMOPLASTIC ELASTOMER COMPOSITION Russian patent published in 2014 - IPC C08L77/02 C08L27/20 C08L27/16 C08K3/22 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining thermoplastic elastomer composition with higher resistance to action of aggressive media, which can be used for manufacturing by methods of casting under pressure and extrusion of gaskets, bushings, cuffs and other mechanical rubber products, operating under conditions of contact with aggressive media. Method of obtaining thermoplastic elastomer composition includes dynamic mixing of aliphatic polyamide with elastic polymer, which is represented by copolymer of hexafluoropropylene with vinylidenfluoride with fluorine content 64-66%, Mooney viscosity at 121°C from 40 to 60 units. In the process of dynamic mixing of said components additionally introduced is mixture of magnesium oxide and calcium hydroxide with ratio 1:2 in amount 2 wt.p. per 100 wt.p. of said copolymer.

EFFECT: obtaining thermoplastic elastomer composition with higher resistance to action of aggressive media and temperatures, and with high physical-mechanical properties.
