Dynamic moduli of dilute aqueous solutions of four poly(ethylene oxide) samples were measured as a function of frequency at four temperatures. From the measurements on two quite monodisperse samples the value of the Peterlin parameter ε was determined using a shifting procedure. A definite decrease in ε was observed when going from 10°C to 40°C. Polydisperse samples were analysed by treating them as consisting of one monodisperse high-molecular mass fraction which does, and a remaining polydisperse lower-molecular mass fraction which does not contribute to the reduced dynamic moduli.
