    • A production method for polypyridinium having a narrow molecular weight distribution and a desired molecular weight is provided. Polypyridinium 3 having a narrow molecular weight distribution and a desired molecular weight is synthesized by allowing a pyridine derivative monomer 2 to polymerize on a polymerization initiator 1 such as a specially designed 4-halopyridinium and the like in the presence of a dissolution accelerating agent, such as tetrabutyl ammonium tetrafluoroborate, that dissolves the polymer formed in a solvent as in the chemical below. where Y represents an anion that dissolves in an organic solvent, X and Z represent halogen atoms, R represents hydrocarbon groups and the like and o is about 1 to 300.
    • 提供了具有窄分子量分布和所需分子量的聚吡啶鎓的制备方法。 通过使吡啶衍生物单体2在诸如特殊设计的4-卤代吡啶鎓等的聚合引发剂1上聚合,在溶解促进剂存在下合成具有窄分子量分布和所需分子量的聚吡啶鎓3, 作为四氟丁基铵四氟硼酸盐,其溶解如在下面的化学品中在溶剂中形成的聚合物。 其中Y表示在有机溶剂中溶解的阴离子,X和Z表示卤素原子,R表示烃基等,o为约1至300。
