The relativistic nuclear mean field model with derivative scalar coupling suggested by Zimanyi and Moszkowski is extended to asymmetric nuclear matter by including the [rho] meson degree of freedom in the Lagrangian. The extended model is then used to studying the Coulomb instability of asymmetric nuclear matter at finite temperature. The critical temperature for the liquid-gas phase transition in nuclear matter and its dependence on the asymmetry parameter are calculated. The limiting temperature [ital T][sub lim], which reflects Coulomb instability of hot nuclei is studied. The calculated results are compared with those given by quantum hadrodynamics (QHD) models.
