The present invention provides a fluorooxane-containing gas which is excellent in water repellency, low dynamic friction property, mold release property, and soil wiping property, and which is excellent in scratch resistance, adhesion to a substrate, and alkali resistance. a polymer composition based on the surface, a surface treatment agent, an article, and an optical article containing the polymer composition. The present invention provides a polymer composition containing a fluorooxyalkylene group, which is characterized in that the polymer composition containing a fluorooxyalkylene group represented by the following average composition formula (1) has a terminal Rf2 group number relative to all terminal groups. The ratio is 30% or more and 75% or less, and includes a polymer having a hydrolyzable decyl group at one end and a polymer having a hydrolyzable decyl group at both ends, [Chemical Formula 1] A-Rf1-B (1) □ (Rf1) Is a divalent linear fluorooxyalkylene group, A and B are Rf2 groups or a group represented by formula (2), and Z is a fluorene-containing alkyl structure or a fluorene-extended aryl structure, and is free of decane. The bond of 2 to 7 bonds of the bond, X is a hydrolyzable group). |
