摘要

<,正,>, The present paper deals with the kinetics of polymerization of acrylonitrile （AN） initialed by the redox system of polypropylene-based vanadyi polyimidodiacetate （PV）-thiourea （TU）in aqueous sulfuric acid in the temperature range from 25 to 40℃. The polymerization rate was measured by varying the concentrations of monomer, vanadyl polyimidodiacetate, thiourea and sulfuric acid. The overall rate of polymerization was summarized asRp=2.2×10,5,e,-6.560/RT, [AN],1.0,[PV],0.50,[TU],1.5,[H,2,SO,4,],2.0,The molecular weight of polyacrylonitrile based on the experimental data was:（?）=k 1/T [pv],0.50,[TU],1.5,[H,2,SO,4,],2.0,These results indicated that the chain radicals are terminated by combination and/or disproportionation rather than chain transfer. The cooperation effect of carboxylic groups and the macromolecular field effect of polymer supporter are the characters of vanadyl polyimidodiacetate such as the case reported in early paper.

The polymerization rate was measured by varying the concentrations of monomer, vanadyl polyimidodiacetate, thiourea and sulfuric acid. The overall rate of polymerization was summarized asRp=2.2×10,5,e,-6.560/RT, [AN],1.0,[PV],0.50,[TU],1.5,[H,2,SO,4,],2.0,The molecular weight of polyacrylonitrile based on the experimental data was:（?）=k 1/T [pv],0.50,[TU],1.5,[H,2,SO,4,],2.0,These results indicated that the chain radicals are terminated by combination and/or disproportionation rather than chain transfer.
