Synthesis and Study of Framework Azomethine Compounds as Ingredients of Rubber Stocks

Bisazomethines derived from D,L-camphor, 2-adamantanone, and aliphatic diamines were prepared. The possibility of using bisazomethines as vulcanization accelerators was examined. The physicomechanical parameters of vulcanizates based on SKI-3 and their resistance to thermal oxidative aging were determined. The influence of the bisazomethine structure on the vul canization rate was found. Among the compounds synthesized, N,N ′-(propane-1,3-diyl)bis(1,7,7-trimethylbicyclo[2.2.1]heptan-2-imine) shows the best set of vulcanization and operation properties.
