Abstract
An unsaturated polyester resin composition having excellent vibration-damping properties, comprising an unsaturated polyester resin (A) having a glass transition temperature (Tg) of 0° C. or more and less than 60° C. In the composition, the unsaturated polyester resin (A) may be blended with an unsaturated polyester resin (B) having a glass transition temperature (Tg) of 150° C. or more and less than 200° C. or an unsaturated polyester resin (C) having a glass transition temperature (Tg) of 200° C. or more. Further, the composition may contain an elastomer (D) having a glass transition temperature (Tg) of −50° C. or more and less than 100° C. Since the unsaturated polyester resin composition has excellent vibration-damping properties and moldability in a wide temperature range, it is very useful to provide molded articles such as vibration-damping structural components, especially automobile engine-related components, having excellent heat resistance and chemical resistance as well as having excellent vibration-damping properties and moldability.
