Kinetics of Peroxide Vulcanization of Natural Rubber
Kinetics of Peroxide Vulcanization of Natural Rubber Cure Characteristics The Monsanto Rheometer (ODR) was used for studying the cure characteristics of the rubber compound. Three important parameters that an ODR curve provides are delta torque (M H-M L), scorch time (ts 2) and the time required to reach a given percentage of delta torque.

Kinetic Studies of the Vulcanization of Natural
Although studies of vulcanization kinetics are of great scientific and practical value, still the efforts of the physical and the organic chemists must supplement each other, so that some day it will be possible to present a complete picture of the vulcanization reactions. Kinetic studies of vulcanization with their quantitative results have always had technical significance.

Non-rubber components tuning mechanical properties
After addition of protein, the acceleration effect of NRC can be verified and mimicked. Through NRC or additional protein controlling vulcanization kinetics, we can tune mechanical properties of NR from soft state to tough state. Therefore, NRC affecting vulcanization kinetics is another essential reason why NR owns superior mechanical properties.

SULFUR VULCANIZATION OF NATURAL RUBBER FOR BENZOTHIAZOLE
The chemistry of accelerated sulfur vulcanization is reviewed and a fundamental kinetic model for the vulcaniza-tion process is developed. The vulcanization of natural rubber by the benzothiazolesulfenamide class of accelerators is studied, where 2-(morpholinothio) benzothiazole (MBS) has been chosen as the representative accelerator. The reaction

Vulcanization
Vulcanization is a chemical process, invented by Charles Goodyear, used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other rubbers via various means. Examples include silicone rubber via room temperature vulcanizing and chloroprene rubber using metal oxides. Vulcanization can therefore be defined as the curing of elastomers; with the terms
