The hyperbolicity of a model for Relativistic Extended Thermodynamics of Polyatomic Gases is here proved for every time direction $\xi_alpha$; moreover, it is proposed an expressions for the production terms of the field equation which encloses as particular cases the variant of the Anderson-Witting model already known in literature, but also a new variant of the Marle model. With these expressions, it is shown that the field equations satisfy automatically the requirement of a non negative entropy production.
