Description
The various end-to-end distances of four-junction polymers are investigated. The sizes of the different kinds of equal length branches and the backbone of two different polymers, with either nine or eleven branches, are estimated by means of both renormalization-group and MC calculations. The comparisons of first-order epsilon = 4 - d predictions with the MC results are satisfactory. The same trends are present in both techniques. The excluded-volume interactions from additional branches further expand the various parts of the chains so that internal branches are larger than external ones. The branch ratios in the eleven-branch case are expanded even more than the corresponding ratios of the nine-branch polymer.
