Abstract
The invention is directed to a process for preparing polyamide polymers, particularly nylon 6, 6 and nylon 6, comprising fluoroether functionalized aromatic repeat units. In one embodiment, 1,6 diaminohexane, adipic acid, and fluoroether functionalized terephthallic or isophthallic acid or diester are reacted to form a polymer. The polymers so formed are useful for imparting soil resistance to polyamides, particularly in the form of films, molded parts, fibers, fabrics, and carpets.
