In situ polymerization of fluorinated acrylic copolymers for the conservation of stone
The experimental results presented on this paper support once again that the in situ polymerization is a technique more favourable than the traditional one, since the polymerization of acrylic monomers inside the stone pores allows putting into the stone an amount of polymer larger than that obtainable by the application of a preformed polymeric material. This improves the consolidating and protective properties of the treatment. On the other hand, it is well known that the protective efficacy of a polymer can be improved if fluorinated compound are used. Our experiments show that either fluorinated monomers can be added to the copolymerizing mixture or a fluorinated polymer can be dissolved in the acrylic monomers. Our data lead to the conclusion that only few percent of fluorinated compound is enough to largely improve the protective properties. This is remarkable since it reduces the cost of the restoration.
