The composition and structure of neutron stars are studied employing different models for the equation of state of neutron star matter allowing for the appearance of hyperons. The models are constructed with simple but realistic parametrizations of the nucleon-nucleon and hyperonnucleon interactions. Solving the equations of hydrostatic equilibrium it is found that there is only one model able to predict a maximum neutron star mass over 2M, in agreement with astronomical observations. This is a model which has a soft nucleonic contribution to the energy density but a stiff hyperonic one and, as a consequence, avoids the hyperonization of matter
