WebHowever, work with natural rubber crosslinked using different vulcanising systems shows that the Guth-Gold type of equation, which has hitherto been used, is inadequate for predicting the modulus of filled rubbers. The discrepancy between different vulcanising systems could be attributed to the effect of carbon black on crosslinking efficiency. WebApr 15, 2004 · Guth and O. Gold, Phys.
