SOUND DAMPING COMPOSITION |
| 摘要 |
<p>A sound damping composition which includes a plasticizer and at least one unsaturated block copolymer having a mono alkenyl arene content of equal to or greater than 60 weight percent and a modulus of less than 125,000 psi. The plasticizer is an aromatic ester or a liquid aromatic resin. The sound damping composition is characterized by having improved sound damping characteristics over sound damping composition employing block copolymers containing conjugated diene homopolymer elastomeric blocks.</p> |
