Abstract:
Acrylic polymers, whether linear or cross-linked, are excellent adhesives. They can be easily fabricated into many different components and shapes. Acrylics have exceptional optical clarity, strength, and dimensional and color stability. They have a convenient liquid-to-solid transition upon curing and can by curved by radiation. Fluorocarbons have a much broader resistance to physical and chemical attack than acrylic polymers, but lack the advantages of acrylic polymers. It is an object of the present invention to substantially increase the fluorocarbon content in acrylic resins, without interfering with the acrylate properties. Another object of this invention is to vary the fluorine content of fluroacrylic resins over wide ranges through the placement of perfluoroalkyl pendant groups of different lengths. These and other objects are achieved by reacting a fluoroaromatic dol and acryloyl chloride in a highly fluorinated solvent with an acid acceptor to form a fluorinated diacrylate ester monomer and purifying the monomer by forming a solution, adding decolorizing carbon to the solution and percolating the solution through activated alumina.
