A model polymer network was constructed from branched chains. Each chain was built on a simple cubic lattice forming a star‐branched polymer consisting of f = 3 arms of equal lengths. The fragment of network under consideration consisted of 1, 2 and 3 star polymers with different topology of connections. The only potential used was excluded volume (athermal chains). The properties of the network were determined by the means of computer simulations using the classical Metropolis sampling algorithm (local micromodifications of chain conformation). The behaviour of linear chains of the same molecular weight was also studied as a state of reference. The influence of attaching the next star‐branched chain to the network on its static and dynamic properties was studied. The short‐time dynamic behaviour of chain fragments was determined and discussed.
