After chloromethylation and amination, five kinds of polynZeric ammes were thus obtained. These polymers were reacted with palladium chloride, and were then reduced. The polymer-supported catalysts synthesized above were used to catalyze the selective hofrogenation Of mesityl oxide under reaction conditions Of 80t and 10kg/cm￣2, using methanol as a solvent.The catalytic activity and MIBK (methyl isobutyl ketone) formation selectivity of the catalysts were examined.
