<P>PROBLEM TO BE SOLVED: To provide a novel polymer containing a sulfur atom and a triazine unit which achieves simultaneously a high refractive index and high transparency in a visible region. <P>SOLUTION: The polymer comprises a structural unit represented by formula (1) (wherein: R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>are each independently a group selected from the group consisting of 1-3C alkyl group and a cyano group; R<SP POS="POST">3</SP>is a 1-3C alkyl group; and m and n are an integer of 0 to 4, where when m and/or n is 2 or more, a plurality of R<SP POS="POST">1</SP>s and/or R<SP POS="POST">2</SP>s present may be the same as or different from each other). <P>COPYRIGHT: (C)2012,JPO&INPIT |
