  Methods for the synthesis of perfluorocarboxylic acid derivatives with reactive trialkoxysilyl groups soluble in organic and organofluorine (1,1,2-trichlorotrif1uoroethane, etc.) solvents have been developed. The contact angles of water and decalin, water absorption, resistance to freezing, and salt-resistance of limestone and plaster samples treated with these compounds were determined. Fluorosilicon organic compounds impart more hydro- and oleophobic properties to the protected surfaces than known organosilicon agents and reliably protect sculptures and architectural monuments from mold and algae deposition.

  开发了具有反应性三烷氧基硅烷基团且可溶于有机和有机氟溶剂（如1,1,2-三氯三氟乙烷等）的全氟羧酸衍生物的合成方法。测定了经这些化合物处理的石灰石和石膏样品的水和十氢萘接触角、吸水性、耐冻性以及耐盐性。氟硅有机化合物相较于已知的硅有机剂，为保护表面赋予了更强的疏水和疏油性能，并能可靠地保护雕塑和建筑纪念物免受霉菌和藻类附着。
