FIELD: chemistry.
SUBSTANCE: thermoplastic elastomer material contains: (a) from 10 to 100 wt % of at least one thermoplastic elastomer based on styrene; (b) from 0 to 90 wt % of at least one thermoplastic homopolymer or copolymer of α-olefin, different from (a); where amount of (a)+(b) equals 100; (c) from 2 to 90 pts. wt of vulcanised rubber in crushed state; (d) from 0.01 to 10 pts. wt of at least one coupling agent which contains at least one unsaturated ethylene; where amounts (c) and (d) are expressed in ratio to 100 pts. wt of (a)+(b).
EFFECT: improved mechanical properties, specifically breaking stress and breaking elongation, increased wear resistance.
