摘要

Polymers used as windows for underwater acoustic transducers must cause minimum reflection of the sound wave, but must also be capable of damping out any flexural vibrations. These requirements can be interpreted as demanding a material that has both matches of sound speed and density with water and moderately high dynamic losses. One good candidate material is a polyurethane with poly(1,2-butyleneoxy)glycol (or PBOG) softblocks. The relationships between the PBOG molecular weight and the sound speed and density of the polyurethanes will be presented.
