(57) [Problem] To provide a water / oil repellent composition which imparts high water / oil repellency to fibers and does not impair the texture. A polymer (A) containing a polymerized unit of a polymerizable monomer having a polyfluoroalkyl group, F (CF 2 ) 10 C H = CH 2 or the like wherein R f1 Q 1 CR 1 = CH 2 of (R f1 is a polyfluoroalkyl group, Q 1 is and a divalent organic group, R 1 is a hydrogen atom.) And a compound represented by (B) , And a medium, and the amount of (B) relative to (A) is 0.1 to 10% by weight. It is. |
