2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/108423We introduce an algorithm for the reduction of computer generated atomistic polymer samples to networks of primitive paths. By examining network ensembles of Polyethylene and cis-1,4 Polybutadiene melts, we quantify the underlying topologies through the radial distribution function of entanglements and the distribution of the number of monomers between entanglements. A suitable scaling of acquired data leads to a unifying microscopic topological description of both melts.4 pages 3 figures.
