Abstract
AbstractIR compounds containing ammonium derivatives of oligoamidephosphates were studied with respect to vulcanization and mechanical characteristics. The ammonium derivatives were obtained as neutral analogues of the corresponding oligoamidephophates. The results indicate an improved efficiency of the neutral products and the possibility of a partial replacement of traditional sulphenamide accelerators with the studied ammonium derivatives, leading to a strong improvement of the fatigue resistance (by more than one order).The addition of such products without reducing the level of the basic accelerator led to additional acceleration—the cure rate increased and the cure time decreased up to three times. Ageing resistance showed a tendency to improve.
