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.

Claims (8)

1. An elastomeric polymer blend, wherein the elastomeric polymer blend comprises from about 50 to about 95 wt % epihalohydrin and from about 5 to about 50 wt % plastic polymer polymethylmethacrylate, wherein the blend is homogenous, and has a vertical rebound of between 0 and about 10% and a Tg between about −20° C. and about 45° C.

2. The elastomeric polymer blend of claim 1 , wherein the epihalohydrin is epichlorohydrin.

3. The elastomeric polymer blend of claim 1 , wherein the epihalohydrin has a Mooney viscosity between 10 and 120.

4. The elastomeric rubber blend of claim 1 , wherein the polymethylmethacrylate has an average molecular weight between 10 3 and 10 7 g/mole.

5. The elastomeric rubber blend of claim 3 , wherein the polymethylmethacrylate has an average molecular weight between 10 3 and 10 7 g/mole.

6. The elastomeric polymer blend of claim 1 , wherein the epihalohydrin and polymethylmethacrylate are homogeneously blended in solution.

7. The elastomeric polymer blend of claim 1 , further comprising one or more filler.

8. The elastomeric polymer blend of claim 7 , wherein the filler is selected from silica or silicate, clay, or combinations thereof.
