In this paper, we study the dynamical entanglements in the interaction between two two-level atoms with a single-mode field in a squeezing-enhanced superposition of coherent state. By using the master equation method and the linear entropy criterion in the Jaynes-Cummings model, we find that the squeezing parameter and relative phase in the single-mode field can effect on the entanglement degrees between subsystems such as atom-field, atom-atom. Besides, the dynamical behaviors of this model are found to be different compared to that of the corresponding squeezing superposition of coherent state.
