Zusammenfassung:Disclosed is a multilayer polymeric structure comprising a plurality of layers comprising at least one layer comprising a stiff polymeric material having a flexural modulus of about 140 kpsi to about 500 kpsi; and at least one layer comprising a soft polymeric material having a flexural modulus of less than 75 kpsi; wherein layers of the stiff polymeric material alternate with layers of the soft polymeric material; and the total thickness of the multilayer polymeric structure is from about 1 mm to about 14 mm. The structure provides improved sound-deadening properties.
