A difunctional epoxy acrylate monomer is prepared by reacting a highly fluorinated diglycidyl either with an excess of acrylic acid in the presence of a suitable catalyst. The acrylate has the following structure; <IMAGE> +TR <IMAGE> where N is an integer from 1 to 30. This monomer is totally miscible with nonfluorinated polyacrylates. Clear, colorless, low refractive index polymers can be prepared by polymerization of this monomer or blends with other acrylates to give products useful as low surface energy coatings, and low refractive index coatings, on a wide range of substrates.
