<P>PROBLEM TO BE SOLVED: To provide a fluorine-containing polymer excellent in a low refractive index, high hardness, scratch resistance and stain resistance. <P>SOLUTION: The fluorine-containing polymer is obtained by an addition reaction of a fluorine-containing compound (A) having two terminal fluorine-containing vinyl groups directly linked to oxygen atoms in the molecule and a compound group (B) having two or more -OH groups in the molecule, and the polymer contains at least a unit expressed by general formula (I). In the formula, Rf<SB>11</SB>represents a perfluoroalkylene group; Rf<SB>12</SB>and Rf<SB>13</SB>each independently represents a fluorine atom, a perfluoroalkyl group or a perfluoroalkoxy group, wherein at least two in Rf<SB>11</SB>, Rf<SB>12</SB>and Rf<SB>13</SB>may be coupled to form a ring; Rf<SB>1</SB>represents an alkylene group having a valency of (n+2) and containing at least one fluorine atom; G represents a crosslinking group; and n represents an integer of 1 to 4. <P>COPYRIGHT: (C)2010,JPO&INPIT |
