Abstract
Electrorheological (ER) measurements have revealed that a solution of a urethane-based polymer having a cyanoethoxy terminal group exhibits an increase in the elastic modulus under an electric field. In contras t, the elasticity of a similar polymer with a methoxy terminal group i s decreased by the field. The opposite ER effects are discussed in ter ms of the induced segmental behaviour of the polymers.
