We study the effects of the three- and fourfold crosslinks on wormlike micelles. This model is worked using a correspondence between magnetic models and equilibrium polymers. We obtain the phase diagrams and the critical behavior of the concentration of extremities and of crosslinks. These crosslinks generate a demixing for both three- and fourfold connections. We show that, due to the difference of parity between the three- and fourfold connections, the behavior is quite different for each case.
