Abstract
A thermoplastic polyester elastomer having a crystalline melting point which satisfies the relationship: y≧200+0.5x, a Vicat softening point which satisfies the relationship: z≧50+1.5x, and a tensile elongation of at least 100% which is measured according to JIS K 6251, in which x is a weight percentage of polymeric units which substantially constitute hard segments of the elastomer; y is a crystalline melting point (°C.); and z is a Vicat softening point (°C.), which elastomer has a high melting point, while it has good heat resistance, water resistance and weather resistance.
