PROBLEM TO BE SOLVED: To obtain the subject composition with markedly improved flame retardancy of the high-melting elastomer, useful as a molding material for boots and the like by specifying the relationship between hard segment constituent wt.%, crystal melting point and Vicat softening temperature. SOLUTION: This elastomer composition is obtained by compounding (A) a thermoplastic polyester elastomer with (B) a triazine group-bearing compound and/or derivative thereof. This composition thus obtained has a crystal melting point shown by the relationship: y>=200+0.5x (x is substantial hard segment constituent wt.% based on the component A; y is crystal melting point ( deg.C) determined by raising temperature from room temperature at a rate of 20 deg.C/min using DSC), Vicat softening temperature shown by the relationship: z>=50+1.5x (z is Vicat softening temperature( deg.C) determined in accordance with the ASTM D1525), and elongation at break (determined in accordance with the JIS K6251) of >=100%; wherein it is preferable that x is 30-95 (wt.%).
