Effect of non‐rubber components on vulcanization kinetics of natural rubber was studied with the use of a Rheometer MDR‐2000. The results show that the rate constants of induction period and curing period of natural rubber (NR) are greater than that of natural rubber extracted with acetone (NR E ), and the activation energies of induction period and curing period of NR are lower than that of NR E . The activation energy of induction period of NR is reduced by16.9% and the activation energy of curing period of NR is reduced by 3.2% compared to the activation energies of NR E . The time t dis of NR is shorter than that of NR E at the same temperature. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
