STUDIES ON STRUCTURE AND PHYSICAL PROPERTIES OF VULCANIZATES CONTAINING COMMINUTED VULCANIZATES

(IV) COMPARISON BETWEEN EXPERIMENTS AND THEORY OF ZERO DIMENSIONAL MODEL OF TRANSFER AND REACTION OF SULFUR IN VULCANIZATES CONTAINING COMMINUTED VULCANIZATES

Abstract

Theory of zero dimensional model of transfer and reaction of sulfur in vulcanizates containing comminuted vulcanizates has been developed in the former paper taking into account the solubility, diffusion, and crosslink reaction of sulfur in each phase. Predicted equations on sulfur concentration and crosslink density in rubber matrix and comminuted vulcanizates are compared with experimental results in this report.
There is found good correlation between calculated results and experimental values. Quantitative relation between solubility, diffusion, and crosslink reaction of sulfur in each phase has been established.
