Starch is sensitive to moisture and is weak to durability in the protection application to ancient relics. Therefore, two fluorosilicone-modified starches are firstly prepared and evaluated for the protection of historic stones. The fluoro-silicone copolymer grafted starch of P(VTMS/12FMA)-g-starch is synthesized by grafting copolymer of vinyltrimethoxysilane (VTMS) and dodecafluoroheptyl methacrylate (12FMA) onto starch. While the fluoro-silicone starch latex of VTMS-starch@P(MMA/BA/3FMA) is obtained by emulsion polymerization of VTMS primarily grafted-starch (VTMS-starch) with methyl methacrylate (MMA), butyl acrylate (BA) and 2,2,2-trifluoroethyl methacrylate (3FMA). The grafting fluorosilicone copolymer onto starch improves obviously their hydrophobic and thermal properties. Comparatively, VTMS-starch@P(MMA/BA/3FMA) film performs higher water contact angle (107 ) and thermal stability (350-430 C) than p(VTMS/12FMA)-g-starch film (72 , 250-420 C) due to the migration of fluorine-containing group onto the surface of film during the film formation. Therefore, VTMS-starch@P(MMA/BA/3FMA) shows much better protective performance in water-resistance, and salt/freeze-thaw resistance for stone samples.

“…Hence, both the oil and the UV absorber serve to protect the wood from photodegradation, but in different manners. Protection against leaching could also be achieved by attaching the UVabsorber to the coating polymer in order to prevent migration of the UV absorber through the protecting film [14]. This, on the other hand, restricts to UV protection in the coating film whereas the interface between the wood and the coating remains unprotected.…”

“…One of the acrylate copolymers frequently used in restoration and preservation of cultural heritage is Paraloid B72 composed of methyl acrylate/ethyl methacrylate [2,5]. Paraloid B72 is nowadays successfully used for treatment of both organic and inorganic materials, in the case of historical metal artifacts it serves as a finishing protective layer.…”

“…The resulting properties of acrylate polymers are determined by the structure of default monomers -monomers with branched-chained alcohol structure create harder polymers compared to monomers with straight-chained alcohol structure. In terms of glass transition temperature T g [°C], polyacrylates have lower T g than polymethacrylates [2]. Acrylate polymers are widely applied in practice because of their suitable properties -reversibility, transparency, hydrophobicity [1], long-term stability, easy applicability and renewability of polymer layer, adhesion to the substrate and modifi ability [3][4][5].…”

Acrylate varnishes are due to their suitable properties frequently used in restoration and preservation on variety of historical objects and materials. Common practice of their application involves using as an adhesive agents, consolidants and protective coatings. The purpose of protective coatings especially on metal artefacts is to reduce access of pollutants to the surface of the artefact. In this paper, coatings prepared from two acrylate polymers Paraloid B72 and Paraloid B48N are compared in terms of permeability for water and level of protective properties against air pollutants. For this purpose, electrochemical impedance spectroscopy and resistometric method were chosen for analysis of the coatings. Obtained results show lower permeability for water in case of Paraloid B72. However, same coating provided lower protection against air pollutants than Paraloid B48N coating.
