The relaxation spectrum at long times has been calculated for comblike micronetworks of Gaussian chains with definite length; L, number of subchains N, and generation order g. The calculation is based on the well-known phantom network approximation; thus excluded volume and entanglements effects are not considered. The longest relaxation time is in the present model of the order N-g and diverges for networks of infinite size. This model gives a reasonable phantom description of a rubberlike network with a large number of dangling ends.
