Process for the synthesis of fluorinated ethers of aromatic acids

摘要

New fluorinated ethers of aromatic acids and diesters are disclosed. These compositions can be applied to, e.g., fibers, yarns, carpets, garments, films, molded parts, paper and cardboard, stone, and tile to impart soil, water and oil resistance. By incorporating the fluorinated ethers of aromatic acids, or diesters thereof, into polymer backbones, more lasting soil, water and oil resistance, as well as improved flame retardance, can be achieved.
