This Demonstration models the transition from a dendrimer to a linear polymer. It was inspired by the already existing Demonstration "Random Branching Process". The difference is that you can specify the number of nodes, which can be interpreted as the molecular weight of the polymer remaining constant during the branching/debranching process. (Use the default number of nodes, 126, to start.) To see the transition, change the branching probability. The final degree of branching is given by a number at the bottom-left of the graphic.
