For the present study two types of rock, from Spain and Romania, selected by regional significance, abundance and importance were characterized by powder x-ray diffraction (PXRD). The samples were prepared by casting the same amount of a silsesquioxane-based polymer obtained through sol-gel approach and radical polymerization of 3-(trimethoxysilyl)propyl methacrylate (TMSPMA) onto powder stones. Due to the distinct stones composition, the different polymer behaviour as regarding to these samples was evi-denced through PXRD techniques. Conclusions concerning acid resistance, stone conserva-tion and durability were revealed by using Match! Software and IUCr/COD/AMCSD data-base.
