Abstract: In this paper the 13C NMR spectra of polyacrylate triphenyl-phosphonium chloride have been studied. The relationship between the structure of macromolecule phosphonium salts and carbon-phosphonium coupling constants was discussed. By the method of inverse gate decoupling of 13C NMR spectra, molecular weight of polyacrylate triphenylphosphonium chloride and block ratio of block polyacrylate triphenylphosphonium chloride were determined.
