| titleOfInvention | A kind of method for measuring azobisisobutyronitrile radical initiation efficiency |
| abstract | The invention relates to a method for measuring the initiation efficiency of azobisisobutyronitrile free radicals, and belongs to the technical field of analysis and testing methods. The method includes the following steps: mixing azobisisobutyronitrile, 2,2-diphenyl-1-picrohydrazide and vinyl acetate to generate a polymerization reaction, and determining when the color of the polymerization reactant changes from purple to yellow At the end of the induction period, the polymerization induction period of different concentrations of free radical scavenger was measured, and the linear regression equation was made with the polymerization induction period and the concentration of the free radical scavenger, and the linear slope of the linear regression equation was recorded as R i . Azobisisobutyronitrile radical initiation efficiency f=R i /(2k d [I]), where R i is the initiation rate, k d is the decomposition rate constant of azobisisobutyronitrile, and [I] is azobisisobutyronitrile The concentration of azobisisobutyronitrile. The assay method has high sensitivity and high detection efficiency, and can accurately determine the azobisisobutyronitrile radical initiation efficiency. |
