The polymer structures considered traditionally for the formulation of protective coatings for the conservation of ancient monuments are generally inadequate to satisfactorily fulfill all the specific requirements for this use, such as durability, water repellence, vopour permeability etc. The results are reported of continuing systematic study of the influence of the macromolecular structure of new acrylicbased fluorinated materials on their photostability end the effectiveness of their protection when employed as coatings for different types of stone. Copolymers of 1,1,2,2-perfluorodecylmethacrylote (XFDM) and of 2,2,2-trifluoroethylmethacrylote (TFEM) with either linear or branched nonfluorinated methacrylates and acrylates were tested and compared with the parent non-fluorinated polymers in order to assess the influence of the number, size and distribution of fluorinated side chains on the ultimate properties of the coating material applied on to different types of stone.
