摘要： A polyfluoroalkyl iodide is reacted with a metal salt of (meth)acrylic acid to form the corresponding polyfluoroalkyl (meth)acrylate. The polyfluoroalkyl (meth)acrylate is separated and recovered from the reaction products by evaporation. Thus, the polyfluoroalkyl iodide can be reacted with the metal salt of (meth)acrylic acid while avoiding water inclusion to produce the polyfluoroalkyl (meth)acrylate. This ester can be copolymerized with an ethylenically unsaturated compound copolymerizable therewith.

摘要： A fluorinated acrylic ester is obtained in high yield by distilling a mixture of fluorinated acrylic esters of the formula CF3(CF2)nCH2CH2OCOCR1=CH2 (wherein R1 represents a hydrogen atom, methyl or halogen atom, and n is an integer of ≥0) wherein the content of impurities (namely, olefins of the formula CF3(CF2)nCH=CH2 and alcohols of the formula CF3(CF2)nCH2CH2OH) is low under such conditions that no polymerization of the ester would occur.
