PROBLEM TO BE SOLVED: To obtain a crosslinked polymer excellent in thermal decomposition resistance, containing a tertiary amine and/or a quaternary ammonium salt and having a tertiary amine structure at both ends of at least one crosslinked portion and, to provide its manufacturing method and use thereof. SOLUTION: The crosslinked polymer contains a tertiary amine and/or a quaternary ammonium salt and has a tertiary amine structure at both ends of at least one crosslinked portion. The crosslinked polymer is obtained, for example, by crosslinking by using epichlorohydrin an alkaline neutralized product of a copolymer of diallyl dimethyl ammonium chloride with diallylamine hydrochloride. the crosslinked polymer is suitably employed, for example, as (A) an ion exchange substance in an ion exchange reaction and as (B) an activating catalyst in a reaction where an active hydrogen is activated. |
