摘要：
The invention relates to a process for preparing methacrylates of fluorinated alcohols, which consists in reacting said alcohols with an excess of methacrylic acid in the presence of phosphoric anhydride, which acts as a catalyst and absorbs the water which has formed. The process is applicable to primary, secondary and tertiary fluorinated alcohols and to alcohols and diols with perfluoroethereal chains.
