The behavior of polymer solutions in elongational flow has been treated quite recently in the literature but scattered in disparate scientific journals not easily accessible. This is very surprising since elongational flow is known to be very effective on polymer chains and thus more interesting than the already wellknown shear flow. This book covers for the first time the subject from the point of view of the various disciplines. It achieves a balance between science, experiment and technology and integrates the fundamental and practical aspects.
