A complex network model of polymer melts without growth

In order to describe the entangled network structure in polymer melts visually, a complex network model without growth is proposed. The analysis shows that the exponential distribution can be exhibited from the statistic of the network after a long time accumulation, the average number of entanglements can be decreased if the probability of deleted edges is not less than that of created edges, and the simulation result and the theoretical one are the same, approximately.
