WebbThe Rouse-Model The polymer chain is treated as a "bead and spring"-model (Fig. 1). Fig. 1: Rouse-chain composed of N R beads connected by springs The force f between the beads is given by "entropic" forces (s. last lecture) fb= R∆r B with = R ∆2 3k T r b (1) where ∆r2 is the mean squared end-to-end distance. http://download.polympart.ir/polympart/ebook/Polymer-Viscoelasticity-Basics-Molecular-Theories.pdf

WebbThe Rouse model is frequently used in polymer physics.. The Rouse model describes the conformational dynamics of an ideal chain. In this model, the single chain diffusion is represented by Brownian motion of beads connected by harmonic springs. There are no excluded volume interactions between the beads and each bead is subjected to a … WebbMolecular Models: Rouse Model (Unentangled) Reptation Model (Entangled) Viscosity Recoverable Compliance Diffusion Coefficient Terminal Relaxation Time Terminal Modulus Plateau Modulus Entanglement Molecular Weight Glassy Modulus Transition Zone Apparent Viscosity Polydispersity Effects Webb1.3 Rouse model The Rouse Model is one of the rst models that tries to describe the dynamics of polymers. It was proposed by Prince E. Rouse in 1953. In essence it’s a chain of Rouse beads connected to each other via harmonic springs. Its use is to give insight in certain statistical 4 clorhexidina bucofaringeo
