The electromechanical response of a polyurethane elastomer was investigated at room temperature and in the temperature range near its glass transition. It was found that the Maxwell stress contribution to the strain response can be significant at tem

A series of linear segmented polyurethanes were synthesized, based on soft segments of polycaprolactone having an average number molecular weight of 2100, or hydroxy–terminated polybutadiene having an approximate molecular weight of 2800. Hara segm

Electrorheological (ER) fluids are typically nonaqueous suspensions that show a reversible viscosity increase upon application of an external electric field. There has been some important basic work on the stress-transfer mechanisms in ER fluids but

Interpenetrating polymer networks (IPNs) are materials composed of two or more crosslinked polymers permanently and intimately intertwined on a molecular level. The resulting distribution of microenvironments can result in a material with a high mech

Dielectric spectroscopy has been used as a probe of molecular behavior in organic molecules for a number of years. 1,2 In conjunction with dynamic mechanical spectroscopy, it has been used to correlate the dynamic mechanical and dielectric relaxation

In the search for broadband damping materials, it is desirable to have polymers with a broad and high loss region in shear or extension, covering the entire temperature and frequency range of interest. Interpenetrating networks, IPN’s, are material

The basic measurement in an impedance tube is a complex reflection coefficient, from which the propagation speed and attenuation are computed. This speed is often identified with the dilatational wave speed in the sample material. This is only approx
