摘要
The oxidation kinetics of natural rubbers prepared by coagulum of fresh natural latex coagulated with formic acid or microorganisms were studied. The maturation time of coagulum is 6, 12, 18 and 24 hours respectively. The results show that the oxidation activation energies of natural rubbers prepared with two coagulation methods increase with increasing maturation time. The oxidation activation energy of natural rubber coagulated with microorganisms is greater than that of natural rubber coagulated with formic acid, but the increment of oxidation activation energy with the increase in maturation time of coagulum of natural rubber coagulated with formic acid is greater than that of natural rubber coagulated with microorganisms.
