Abstract
1. The rate of volatilization of phenyl-2-naphthylamine from a rubber slab depends on the flow rate of gas over the slab, the slab thickness, and the initial concentration of the ingredient. The activation energy of the volatilization process is 14.0 kcal/mole. 2. The rate of volatilization of phenyl-2-naphthylamine diminishes in the following polymer series: polyethylene > fluoroprene rubber > SKB > SKS-30 > SKN-26 > Nairit. 3. The volatilization rate drops sharply with increase of the density of the vulcanization network, and decreases in presence of fillers. 4. The mechanism postulated for volatilization of ingredients from polymers is confirmed by theoretical calculations.Keywords
