Linear Viscoelastic Properties of Polybutadiene Solutions
The study of the viscoelastic properties of polymer solutions has a double interest: from a theoretical point of view, the variations of the elastic (limiting compliance, plateau modulus) and viscous (zero-shear viscosity) parameters as a function of polymer concentration, are a definite test for the various theories on the relaxation and diffusion of long and flexible chains. From a practical point of view, such studies will allow to better understand the effects of the addition of plastifiers on the melt rheology of commercial polymers (viscosity, die swell, glass transition temperatures, etc...).
