<P>PROBLEM TO BE SOLVED: To provide a releasable composition for an adhesive low in biological and environmental risks, exhibiting good releasability to silicone-based adhesives, and excellent in water repellency and oil repellency, transparency and adhesion. <P>SOLUTION: The releasable composition for an adhesive is composed of a copolymer as an effective component of a monomer mixture containing: (1) 50 to 99.5 mass% of a polyfluoroalkylvinyl monomer represented by formula (1), wherein R is hydrogen or methyl, and n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 0 to 3, and c is an integer of 1 to 3; (2) 0.5 to 50 mass% of an organosilicone-based vinyl monomer containing at least one hydrolyzable group bonded to a silicon atom in the molecule; and (3) 0 to 49 mass% of a non-silicon-based or organosilicon-based vinyl monomer copolymerizable with the (1) and (2) components and containing no hydrolyzable group bonded to a silicon atom. <P>COPYRIGHT: (C)2012,JPO&INPIT |
