摘要：

The kinetics of the decrease in the molecular mass of three nitrile rubber samples, containing, respectively, 20, 28 and 39 mol% of acrylonitrile, has been studied viscosymetrically during their ozonization in solution. By comparing the functional groups obtained during ozonolysis of the C equals C bonds with the amount of the ozone consumed, it has been found that approximately 1 mole of ozonides or 2 moles of aldehydes are formed from 1 mole of reacted ozone. An attempt has been made to prove the authors' suggestion that the intensity of the ozone degradation in solution of polybutadiene elastomers with predominantly 1,4-trans bonded butadiene, is considerably higher than that of the 1,4-cis-polybutadiene rubbers.
