Several samples of natural rubber vulcanizates were prepared. A and B samples are cured with sulfur, and C is cured with TMTD (tetramethyl thiuram disulfide) and D is natural rubber cured with peroxide.<BR>The cross-linking densities, n (0), were measured for these four samples extracted with : acetone and unextracted. The values of n (0) calculated by the Flory-Rehner swelling method were compared with those obtained by the mechanical means.<BR>The probabilities of the ratio of both scissions were indicated by k<SUB>A</SUB>, k<SUB>B</SUB> and k<SUB>c</SUB> for three samples except D. The degradation of the polymer structures was discussed for the values of k<SUB>A</SUB>, k<SUB>B</SUB>, k<SUB>C</SUB> obtained from the theoretical equation derived in the former paper.
