Patent ID: 8710174

Claim:
A triazine ring-containing polymer characterized by comprising repeating unit structures represented by the following formula (2): wherein R and R′ independently from each other mean a hydrogen atom or an alkyl, alkoxy, aryl or aralkyl group, R″ means an alkyl, aralkyl, aryl, alkylamino, alkoxysilyl-containing alkylamino, aralkylamino, arylamino, alkoxy, aralkyloxy or aryloxy group, and Ar means at least one selected from the group consisting of groups represented by the following formulas (6) to (12) and (14) to (19): wherein R 16 to R 76 and R 81 to R 128 independently from each other mean a hydrogen or halogen atom, or a carboxyl, sulfone, branched or unbranched C1 to C10 alkyl or branched or unbranched C1 to C10 alkoxy group, W 1 means NR 129 in which R 129 means a hydrogen atom or a branched or unbranched C1 to C10 alkyl group, W 2 and W 3 independently from each other mean a single bond, CR 130 R 131 in which R 130 and R 131 independently from each other mean a hydrogen atom or a branched or unbranched C1 to C10 alkyl group with a proviso that these alkyl groups may be fused together to form a ring, C═O, S, SO, SO 2 , or NR 129 in which R 129 has the same meaning as defined above, X 1 and X 2 independently from each other mean a single bond, a branched or unbranched C1 to C10 alkylene group, or the following formula (20): wherein R 132 to R 135 independently from each other mean a hydrogen or halogen atom, or a carboxyl, sulfone, branched or unbranched C1 to C10 alkyl or branched or unbranched C1 to C10 alkoxy group, and Y 1 and Y 2 independently from each other mean a single bond, or a branched or unbranched C1 to C10 alkylene group.
