| abstract |
An acrylic type self-adhesive which comprises a polymer comprising (a) units of at least one compound of the formula:n wherein R' is a hydrogen atom or a methyl, ethyl or propyl group, 1 is an integer of 1 to 5, s is 0 or 1, and Rf is -(CF 2 ) m X or -(CF 2 ) p O(CF 2 ) n F (wherein m is an integer of 1 to 10, X is a hydrogen or fluorine atom or a hexafluoroisopropyl group, n is an integer of 1 to 5 and p is an integer of 1 to 3), and optionally units of (b) at least one compound of the formula:n wherein R' is a hydrogen atom or a methyl, ethyl or propyl group and R' is -OH, -NH 2 , -NHCH 2 OH, -OCH 2 CH 2 OH,n n or -OCH 2 CH 2 N(CH 3 ) 2 , said polymer having an intrinsic viscosity of 0.1 to 1.0, which shows excellent oil resistance and water resistance. |
