Shapes of branched polymer networks — •Christian von Ferber¹ and Marvin Bishop² — ¹AMRC, Coventry University, Coventry, UK — ²Department of Computer Science and Mathematics, Manhattan College, New York, USA

We investigate the shapes of polymer networks embedded in two- and three-dimensional space as function of their architecture. To this end we employ both analytical methods as well as the Monte Carlo pivot algorithm to investigate continuum, tangent hard-sphere branched polymers both in the ideal and the excluded volume regimes.

The mean square radius of gyration, the g-ratio, and the form factors are evaluated. The MC data agree well with the exactly determined form factors. The form factors reveal the influence of the polymer structure at short distances.
