ANALYSIS OF FOAMING MACROKINETICS OF ELASTOMERIC MATERIALS
Abstract
Macrokinteic parameters of the process of foaming vulcanizates with azodicarbonamide under isothermal conditions in elastomeric materials based on nitrile rubber were determined with use of a melt flow indexer and a moving die rheometer. For compositions differing in the content of zinc oxide as an activator of vulcanization and pore formation processes, the values of the rate constant (k) and reaction orders (n) were calculated, and the extremal nature of the dependence of the activation energy of the pore formation process on the concentration of the activator was established.
