Due to the interfacial tension, immiscible blends can show an elastic recov
ery that is substantially larger than that of their pure components. Here i
t is attempted to relate the elastic recovery after steady shear flow to th
e underlying morphology. On the one hand, the predictions of the Palierne a
nd the Doi-Ohta models are calculated for the flow conditions during recoil
. On the other hand, systematic recoil experiments after steady state shear
ing have been performed on a model blend. As the component polymers hardly
show any recoil under the stresses applied in these tests, the measured rec
overy can be attributed completely to the action of the interface. Comparis
on of the model predictions with the experimental results shows that the re
coverable strain can be derived quantitatively from the linear Palierne the
ory. Although the droplet deformation remained limited during the preshear,
the retardation time predicted by this model has to be multiplied by the a
spect ratio of the droplet phase to the power 2/3 to describe the experimen
ts. For conditions in which the material does not show an intrinsic length
scale, particular scaling relations as derived from the Doi-Ohta theory are
found to apply also to recoil.
