Dynamical properties of branched polymeric clusters in dilute regime
Michel Delsanti, J. P. Munch · Journal de Physique II · 1994
Static and dynamical properties of randomly branched polymers in dilute solutions were investigated by light scattering experiments. In the intermediate scattering regime, the main result is that the time dependence of the dynamical structure factor of the polymer is a function only of the reduced variable Ωt, Ω being a characteristic frequency which varies with the scattering vector q as q2.9±0.1 The dynamical behavior is very similar to that observed with linear polymers. This shows that branching does not affect dynamics, and hydrodynamic interactions between monomers are dominant as for linear polymers.
