摘要：

Spontaneous coagulation NR, acid coagulation NR and constant viscidity NR were prepared and their properties were studied. The results show that acid coagulation NR can possess best anti-aging performance, while spontaneous coagulation NR may have good mechanical properties and high cure rate. As to the constant viscidity NR, its mechanical properties and cure rate decreases compare to the NR without the addition of hydroxylamine hydrochloride. For all samples, the cure process can be divided into two stages: the stage I following first-order kinetics and the stage II following n not equal 1 order. Besides, with the prolonging of maturation process, the mechanical properties, the cure rate and the maximum torque of spontaneous coagulation NR increase gradually, while the nitrogen content and the PRI decline.
