Abstract The characteristics of entanglement structure in polycarbonate/epoxy semiinterpenetrating polymer network at molecular level have been investigated by dynamic mechanical spectrum. It is found that the relaxation of entanglement chains is a kind of synergetic relaxation, which will induce additive internal friction and decrease the apparent activation energy and T_g. The loss areas can represent the degree of interpenetration between the different segments at molecular level.
