FLUORINE-CONTAINING ETHER COMPOSITION, METHOD FOR PRODUCING SAME, COATING LIQUID, BASE MATERIAL HAVING SURFACE TREATMENT LAYER, AND METHOD FOR PRODUCING SAME

摘要

Provided are a fluorine-containing ether composition suitable for use in a surface treatment for imparting water and oil repellency to the surface of a base material, a method for producing said fluorine-containing ether composition, and a coating liquid including said fluorine-containing ether composition. Further provided are a base material having a surface treatment layer, and a method for producing the same. Said composition includes two or more fluorine-containing ether compounds which are represented by A-O-Q-(CbF­2bO)d-X-O-B10, where B10 is different. X is a divalent organic group that does not have CF2O. B10 is -CH2CH2CH2SiLmRn, -CH2CH(SiLmRn)CH3, -CH2CH=CH2, or -CH=CHCH3. A is a perfluoroalkyl group or group B10. Of the total quantity of group B10 in said composition, the proportion of -CH2CH2CH2SiLmRn is 90-99 mol%, and the proportion of -CH=CHCH3 is 1-10 mol%. L is a hydrolyzable group, and R is a monovalent hydrocarbon group. b is an integer from 1 to 10, and d is an integer from 1 to 200.
