Abstract
The invention provides a surface treatment agent wherein a fluorooxyalkylene group-containing polymer or a fluorooxyalkylene group-containing polymer composition comprising the polymers, which is controlled of a temperature range of vaporization of fluorooxyalkylene group-containing polymer(s). The fluorooxyalkylene group-containing polymer has a fluorooxyalkylene structure represented by —(OCF2)p(OCF2CF2)q— and hydrolysable groups bond to a silicon atom represented by the formula at least one terminal. The polymer composition shows a decrease of 75% or more in weight, relative to the total weight of the polymer, in a temperature range of from 150 to 350 degrees C. when this is heated at a rate of 2 degrees C. per minute and a pressure of 0.1 Pa or less. The present surface treatment agent forms a coating having water- and oil-repellency and scratch resistance regardless of a vapor deposition conditions, in particularly by a vapor deposition at a mild temperature such as 350 degrees C.
