Abstract

A highly damping homogenous elastomeric polymer blend. The elastomeric polymer blend comprises from about 50% to about 95 wt % epihalohydrin and from about 5% to about 50 wt % polymethylmethacrylate. The blend is homogenous and has a vertical rebound between 0 and about 10% and a Tg between about −20° C. and about 45° C. when measured by rheology.
