Based on the Solar Standard Model we developed a solar model in hydrostatic equilibrium using two polytropes that describes both the "radiative" and "convective" zones of the solar interior. Then we apply small periodic and adiabatic perturbations on this bipolytropic model in order to obtain proper frequencies and proper functions. The frequencies obtained are in the "p-modes" range of low order l<20 which agrees with the observational data, particularly with the so called five minutes solar oscillations. Key Words: Solar Standard Model, Lane-Emden, Non Radial Oscillations, p-modes.
