Abstract
The correlation between the mechanical properties of revulcanized SBR, total and polysulfidic crosslink density, gel fraction of original vu lcanizate, ultrasonically devulcanized, and revulcanized rubber is des cribed. Under some processing conditions the tensile strength of revul canized SBR is found to be much higher than that of the original vulca nizate with elongation at break being practically intact. A model expl aining the increase in mechanical properties of revulcanized rubber is proposed.
