The computed dependencies of elastic characteristics of branched-network polymers were obtained on the basis of the Takayanagi series model. The moduli ratio (gamma) for branched-network and branched polymers increases as a result of an increase of the moduli ratio of network and branched phases (E*(net)/E*(br)) and the network phase fraction (V-net). The gamma-increase as a function of V-net is larger than in the case of the E*(net)/E*(br) dependence. On the basis of computed dependencies, the experimental results for the radiation crosslinked SBS block copolymer were considered. The experimental results agree with the computed de pendencies for the heterogeneous branched-network polymers with E*(net)/E*(br) approximate to 20. The influence of entanglements on the elastic characteristics of branched-network polymers is discussed.
