Polarimetric observations of cometary comae may be used to infer dust particles properties through experimental simulations. Cometary organic solid materials are poorly known. Here different organic materials found in nature or synthetic are studied. Their light scattering response was correlated to their chemical composition (under heating or not). Some cometary dust analogues were obtained by mixing them with silicates and lifted in the PROGRA2 light scattering experiment.
