The temperature dependence of the \ensuremathφ meson mass and its decay width (\ensuremathφ\ensuremath→K\mathrmK\ifmmode\else\textasciimacron\fi) have been studied from an effective nonlinear chiral Lagrangian in SU(3). The effective mass has been obtained from the pole position of the full propagator. The width has also been calculated. It has been found that the mass decreases with temperature very slowly whereas the decay width increases quite sharply. Possible consequences on the QGP signals are discussed.
