Disclosed is a film dressing comprising a film dressing body. The film dressing body () comprises a film () and a pressure-sensitive adhesive layer () provided on one side of the film (). The film dressing further comprises a release liner () covering the pressure-sensitive adhesive layer () on its adhesive face, and a carrier () covering the backside of the film (). A carrier division part () is provided to divide the carrier () into a carrier first part () and a carrier second part (). A flap layer () is stacked so as to cover the carrier division part (). A flap layer division part () is provided in the flap layer () to divide the flap layer () into a flap layer first part () and a flap layer second part () which are partially joined respectively on the carrier first pat () and the carrier second part (). Preferably, division parts () are provided in the release liner ().

Disclosed is a fluorine-containing polymer having: (A) a repeating unit derived from a fluorine-containing monomer which is represented by the following formula:CH&#x2550;C(&#x2014;X)&#x2014;C(&#x2550;O)&#x2014;Y&#x2014;[&#x2014;(CH)&#x2014;Z&#x2014;]&#x2014;(CH)&#x2014;Rf&#x2003;&#x2003;(I)(B) a repeating unit derived from a monomer containing no fluorine atom, and if necessary (C) a repeating unit derived from a crosslinkable monomer. This fluorine containing polymer has excellent water repellency, oil repellency and antifouling property.

The present invention relates to a process for continuously producing a perfluoroalkyl iodide represented by the general formula R(CFCF)I, wherein Ris a Cperfluoroalkyl and n is an integer from 1 to 4, the method comprising continuously supplying a perfluoroalkyl iodide as a telogen represented by the general formula RI, wherein Ris as defined above, and tetrafluoroethylene as a taxogen to a tubular reactor packed with a metal catalyst comprising a powdery spherical metal or a sintered metal; and conducting telomerization at a temperature of 60 to 160&#xb0; C. under a pressure of 0.1 to 5 MPa (gauge pressure). According to the present invention, medium-chain perfluoroalkyl iodides can be continuously and efficiently produced with little generation of impurities, such as hydrogen-containing organic compounds and the like.
