Title:
FLUORINATED POLYETHER POLYESTER
Document Type and Number:
Japanese Patent JPH0220519
Kind Code:
A
Abstract:
PURPOSE:To improve oil and water repellency, frictional properties, abrasion resistance, durability, heat resistance, elasticity and adhesion, by incorporating F into a polyether polyester. CONSTITUTION:About equimolar amt. of 5-(perfluoroalkenyloxy)isophthalic acid or its derivative of formula I (wherein Rf is perfluorohexenyl, C6F11 or perfluorononenyl, C9F17 and X is OH, Cl, methoxy or ethoxy), such as 5-(perfluorohexenyloxy)isophthalic acid, is reacted with a diol of formula II (wherein R is H or methyl and n=2-140), if necessary, in the presence of a catalyst such as 0.005-0.1wt.% Zn acetate. The resulting polymer has the structure of formula III (wherein Rf and n are as defined above and m>=2).
