<P>PROBLEM TO BE SOLVED: To provide a copolymer improved in heat resistance and mechanical strength and usable as a member for an electric-electronic component. Ž<P>SOLUTION: The copolymer comprises at least a first block having a first repeating unit and a second block having a second repeating unit, and the first repeating unit is represented by a formula 1, while the second repeating unit is furan derivative. In the formula 1, R represents (CH<SB>2</SB>)x (x=2-20), and p and q each represents a natural number of 1-40. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
