WATER-REPELLENT, OIL-REPELLENT AGENT COMPOSITIONS AND MANUFACTURING METHOD THEREFOR

摘要

To provide a water/oil repellent composition which is capable of imparting sufficient dynamic water repellency and post-air-drying water repellency to the surface of an article and which presents a low environmental impact, and a method for its production. A water/oil repellent composition which comprises a copolymer having structural units based on the following monomer (a), structural units based on the following monomer (b) and structural units based on the following monomer (c), and a medium, wherein the molar ratio of the structural units based on the monomer (a) to the structural units based on the monomer (b) (i.e. (a)/(b)) is at least 1:
monomer (a): vinyl chloride;
monomer (b): a vinyl ether having no polyfluoroalkyl group and having a crosslinkable functional group; and
monomer (c): a monomer having a polyfluoroalkyl group.
