Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain copolymers excellent in mechanical stability and heat stability and useful as electroluminescent materials by using copolymers comprising specified chain-structure repeating units and optionally specified repeating units. SOLUTION: These (co)polymers each comprises 0.5-100mol% at least one type of chain-structure repeating units represented by formulas I and/or II and optionally 0-99.5mol% (the total of the molar ratio is 100%) repeating units represented by formula III. In the formulas, R , R and R , which are independent of each of other, are each H or a 1-6C alkyl, R is H, a 1-30C alkyl, a 6-18C aryl or a 1-30C alkoxyl; M is a 1-30 C alkoxycarbonyl which may be substituted with CN, hydroxyl or the like; Y is oxygen, sulfur or -NR (wherein R is H or a 1-6 C alkyl); A and A , which are independent of each other, are each a 6-18 C arylene, a 1-30 C alkylene or the like; and L and L , which are independent of each other, are each a light-emitting group).
