摘　　要：The sodium salt of poly(acrylic acid) has to be converted to poly(acrylic acid) with ion-exchange resin to get clear MALDI/TOF mass spectrum. The average molecular weight, polydispersity and end-group can be determined based on the spectrum.The sodium salt of poly(acrylic acid) has to be converted to poly(acrylic acid) with ion-exchange resin to get clear MALDI/TOF mass spectrum.
