Claim Text:
1. A surface treatment agent comprising a fluorooxyalkylene group-containing polymer and/or a product obtained by partial hydrolysis and condensation of the polymer, wherein the fluorooxyalkylene group-containing polymer has a fluorooxyalkylene structure represented by —(OCF 2 ) p (OCF 2 CF 2 ) q —; wherein p and q are, independently of each other, an integer of from 5 to 80 and a total of p and q is 10 to 100, and these parenthesized units may be sequenced at random; and at least one group represented by the following formula (1) at at least one terminal; wherein R is an alkyl group having 1 to 4 carbon atoms or a phenyl group, X is a hydrolysable group, a is 2 or 3, and c is an integer of from 1 to 10; and 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 heated at a rate of 2 degrees C. per minute and a pressure of 0.1 Pa or less.
