We study the viscoelastic relaxation dynamics of scale-free copolymer networks in generalized Gaussian structures framework. focus on real and imaginary components complex dynamic modulus G^{*}(ω): storage loss moduli. Our chosen network model builds distinct types hyperbranched copolymers by a careful tuning construction parameters, such as γ, which controls node connectivity, or minimum allowed degree K_{min} maximum K_{max}. These together with parameters that govern monomer-type distribution, provide significative behaviors. By only varying γ we change topology local region high frequencies constant slope intermediate frequency become more evident. Both K_{max} play an important role, especially domain. The ratio σ between friction coefficients ζ_{A} ζ_{B} A B beads gives birth to new features, as, quasiplateaus peaks along shift toward lower higher depending value. η number monomers influences size for it is responsible symmetry two modulus.
