Abstract: An amorphous polyester composition according to the present invention comprises (A) a low crystalline polyolefin modified with unsaturated carboxylic acids, (B) an amorphous polyester, (C) a silane coupling agent and (D) an optional inorganic filler, wherein (A) forms a matrix phase and (B) forms a domain phase. This amorphous polyester composition has excellent adhesion properties to different materials such as metal and has excellent damping performance, and therefore a damping material having excellent initial adhesion properties and water-resistant adhesion properties and excellent damping performance, particularly at high temperatures can be obtained from such an amorphous polyester composition.
