摘要：

In the reported experiments, the radiation chlorination of vulcanized natural rubber has been carried out by treating its surface with gaseous chlorine. It has been found that the radiation-chloriantion is suitable for modifying the surface of natural rubber. Rhe tensile stress-strain properties, fastness to water, resistance to accelerated heat ageing in air, hardness, friction coefficient and cross-linking density have been determined. The friction coefficient of the chlorinated rubber was three times lower than that of unmodified rubber. The optimal conditions for chlorination have been found to be dose in the range of 80 divided by 1000 GY and time of 15 minutes to 1. 5 hour. Under these conditions, the degree of chlorination in the range of 0. 15 - 1. 2% by weight hs been obtained.
