Drag on a Tethered Chain Moving in a Polymer Melt
Résumé
A chain of N monomers is attached to a small colloïdal particle, and is pulled (at a velocity V) inside a polymer melt (chemically identical, with P monomers per chain). The main parameter for this problem is the number X(V) of P chains entangled with the (N) chain. Earlier estimates of X are criticized, and a new form is proposed: at large N(N>N2e), we are led to a “Stokes” regime, X=N1/2, while at smaller N(N
