Let f:I I be a C^2 multimodal interval map satisfying polynomial growth of the derivatives along critical orbits. We prove the existence and uniqueness of equilibrium states for the potential _t:x-t|Df(x)| for t close to 1, and also that the pressure function t P(_t) is analytic on an appropriate interval near t = 1.
