Description
Summary:The effect of some dinitrodiamines and dinitrodiamides on dynamic properties of vulcanized rubber have been investigated. Rubber compounds based on NR/BR were used for these experiments. It has been established that only the use of dinitrodiamines contribute to the increase of impact resilience in comparison with the unmodified compound. The results of carbon gel content assessment suggest that, under given conditions, dinitrodiamides do not form bonds between rubber and carbon black and, therefore, do not influence the dynamic properties of vulcanized rubber. © 2001 John Wiley & Sons, Inc.
