<P>PROBLEM TO BE SOLVED: To provide a fluorooxyalkylene group-containing polymer composition, a surface treatment agent, an article and an optical article. <P>SOLUTION: The fluorooxyalkylene group-containing polymer composition is represented by average composition formula (1), wherein the number of the terminal Rf<SP POS="POST">2</SP>group relative to a total number of the terminal groups is 30-75%, and the polymer composition includes a one-terminal hydrolyzable silyl group-containing polymer and a both-terminal hydrolyzable silyl group-containing polymer. (In formula (1), Rf<SP POS="POST">1</SP>represents a divalent linear fluorooxyalkylene group containing 5-100 repeating units of -C<SB POS="POST">d</SB>F<SB POS="POST">2d</SB>O- (d is an integer of 1-6 and may be different from each other in the repeating units); and A and B represent, independently of each other, an Rf<SP POS="POST">2</SP>group or a group represented by formula (2), wherein Rf<SP POS="POST">2</SP>is selected from F, H and a monovalent fluorine-containing group having a -CF<SB POS="POST">3</SB>or -CF<SB POS="POST">2</SB>H group at the terminal, Q represents a divalent organic group, Z represents a divalent to heptavalent linking group having a silalkylene structure or a silarylene structure but no siloxane bond, R represents a 1-4C alkyl group or a phenyl group, X represents a hydrolyzable group, Y is a linking group represented by C<SB POS="POST">c</SB>H<SB POS="POST">2c</SB>or C<SB POS="POST">2</SB>H<SB POS="POST">4</SB>-C<SB POS="POST">r</SB>F<SB POS="POST">2r</SB>-C<SB POS="POST">2</SB>H<SB POS="POST">4</SB>, a is 2 or 3, b is an integer of 1-6, c is an integer of 1-10, and r is an integer of 1-6). <P>COPYRIGHT: (C)2013,JPO&INPIT |
