The temperature dependence of the nuclear matter isovector symmetry energy coefficient (A{sub 0,1}) is investigated in the framework of the generalized nuclear polarizability with Skyrme interactions, as worked out in previous articles [F. L. Braghin, Nucl. Phys. A665, 13 (2000); Phys Rev. C 71, 064303 (2005); Int J. Mod. Phys. E 12, 755 (2003)]. The variation of A{sub 0,1}(T) is very small (of the order of 1 MeV) for temperatures (T) in the range of 0 and 18 MeV. Different behaviors with temperature are found to strongly depend on the Skyrme parametrization, in particular at densities lower than the saturation density {rho}{sub 0}.
