Chemoselective polycondensation of 2-amino-4,6-dichloro-1,3,5-triazine (ADCT) was investigated with various aromatic diamines such as 4,4′-oxydianiline (ODA), 9,9-bis(4-aminophenyl)fluorene (BAFL), 4,4′-(hexafluoropropane-2,2-diyl)dianiline (BisAF), and bis(4-aminophenyl)sulfone (SODA) in the presence of potassium carbonate as a base. High-molecular weight perfectly linear polyguanamines (Mn ≈ 46000) were successfully obtained for the polycondensation of ADCT with BisAF, while the polycondensation of ADCT with BAFL afforded branched polyguanamines with a degree of branching of from 0.02 to 0.17.
研究了 2-氨基-4,6-二氯-1,3,5-三嗪(ADCT)与各种芳香族二胺(如 4,4′-氧二苯胺(ODA)、9、9、9-双(4-氨基苯基)芴(BAFL)、4,4′-(六氟丙烷-2,2-二基)二苯胺(BisAF)和双(4-氨基苯基)砜(SODA)等芳香族二胺进行了研究。ADCT 与 BisAF 的缩聚反应成功地得到了高分子量的完全线性聚鸟嘌呤胺(Mn ≈ 46000),而 ADCT 与 BAFL 的缩聚反应则得到了支化度为 0.02 至 0.17 的支化聚鸟嘌呤胺。
