Abstract

Thermoplastic elastomers containing hard segments formed from polyalkylenes and soft segments formed from elastomeric polymers near their gelation point are formed. Compositions containing these materials are elastomeric and exhibit excellent damping capabilities over a wide range of temperatures and frequencies.
