| Abstract: | The loaded catalyst was prepared by loading Pd2＋ on the ion exchange resin of polyst yrene and used in the copolymerization of carbon monoxide (CO) with styrene (ST) .The catalytic activity and usable life of the loaded catalyst were investigated .Additionally the reuse of the waste Pd2＋ in the copolymerization was st udied by using the ionexchange resin.The results show that the Pd2＋ loaded catalyst has some catalytic activity and reusability.The ion exchange re sin D-72 can adsorb Pd2＋，Cu2＋，etc,in the waste of the copolymerization.The catalytic activity of the reused catalyst can reach 473.93 g／（g Pd*h）． |
