Abstract
Disclosed is a method for improving vibration damping of a substrate, such as the underbody of an automobile. The method comprises applying a plastisol which comprises a polymeric component and a plasticizer. The fused plastisol has improved damping behavior as determined using Dynamic Mechanical Thermal Analysis. Novel plastisols and novel plasticizers are also disclosed.
