The relaxation spectrum has been calculated for treelike networks of phantom Gaussian chains subject to Rouse-Zimm dynamics using an extension of earlier work by Graessley by taking into account the bifunctional junctions dividing each chain between Φ-functional junctions into n subchains of equal length. The relaxation spectrum and stress relaxation modulus have been calculated for varying number n of subchains. It has been found that bifunctional junctions considerably broaden the relaxation spectrum and give a more realistic description of the spectrum at shorter times
