Dynamics of Regular Hyperbranched Polymers — •Florian Fürstenberg, Maxim Dolgushev, and Alexander Blumen — Theoretische Polymerphysik, Universität Freiburg, Hermann-Herder-Str.3, D-79104 Freiburg, Deutschland

Theoretical investigations of hyperbranched polymers are enjoying growing attention. Up to now, analytic work focused on regular fully-flexible hyperbranched polymers such as dendritic structures. Here we investigate the dynamics of semiflexible dendrimers of arbitrary functionality f and generation g. We focus on the solution of the corresponding Langevin equations which can be formulated in an analytic form^[1]. Moreover, we show that the corresponding diagonalization problem can be drastically simplified by using a complete set of eigenmodes, which is similar to the set for fully-flexible dendrimers known from the literature^[4,5]. Another advantage of our diagonalization scheme is that it provides automatically the eigenvalues’ degeneracies^[4]. The presented scheme for dendrimers paves the way for theoretical investigations of more complex polymeric architectures^[5].
