Abstract

The kinetics of the activity of the butyl rubber (BR) curing system without and with various amounts of antioxidant P-23 at temperatures of 55 and 80°C was studied. The induction period of the vulcanization of the BR samples in the presence of sterically hindered phenol was found to exceed that for the samples without phenol. With rising temperature the rate of the rubber vulcanization tends to increase due to an increase in the initiation rate.

在空间受阻的2,4,6-三叔丁基苯酚存在下丁基橡胶固化体系中亚硝基自由基的形成动力学

摘要

研究了在55和80℃下，不添加和不添加各种抗氧化剂P-23的丁基橡胶（BR）固化体系的动力学。发现在存在位阻酚的情况下，BR样品的硫化诱导期超过了不含酚的样品。随着温度的升高，由于引发速率的增加，橡胶的硫化速率趋于增加。
