The polymerization of acrylonitrile （AN） in aqueous nitric acid initiated by metavanadate-containing anion exchange resin （PV）-thiourea （TU） redox system at 20—40℃. has been investigated. The overall rate of polymerization （R

The kinetic parameters differed from those of V

-TU system indicated that the generation of the primary radicals is mainly a difffusion-controlled reaction. The effect of macromolecular field arisen from the polymer matrix exerts a great influence on the polymerization process.
