<p>PROBLEM TO BE SOLVED: To provide a polyester elastomer composition having both excellent transparency and a high surface hardness of a molded product.SOLUTION: There is provided a polyester elastomer composition which comprises a polyester elastomer, an organic carboxylic acid alkali metal salt and a glycidyl group-containing styrene-acryl-based polymer, where the amount of alkali metal salt of an organic carboxylic acid is 0.1 to 5 pts.mass and the content of the glycidyl group-containing styrene-acryl-based polymer is 0.3 to 4 pts.mass based on 100 pts.mass of the polyester elastomer, the polyester elastomer contains a dicarboxylic acid component and a glycol component as constitutional components, the content of an aromatic dicarboxylic acid is 70 mol% or more as the dicarboxylic acid component, the content of a polyoxyalkylene glycol is 5 to 35 mol% as the glycol component, the content of a straight-chain alkylene glycol is 40 to 75 mol% and the content of an alkylene glycol having an alkyl group at the side chain is 5 to 25 mol%.</p> |
