Effect of non‐rubber substances on vulcanization kinetics
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 effect of bound rubber on vulcanization kinetics
The results of cure kinetic behavior demonstrate that the loading of silica suppresses the vulcanization rate compared to neat rubber. Under the same filler content, the higher the bound rubber content, the more obvious the inhibitory effect on vulcanization reaction.

The Effect of Ingredients Mixing Sequence in Rubber
The effects of mixing temperature, vulcanization temperature, and the carbon black type upon the kinetics were also studied by using rheography and an autocatalysis reaction model approach. The results showed that this model is good in providing information on vulcanization reaction kinetics of natural rubber. High vulcanization temperature resulted in high reaction rate constant.

The Action of Vulcanization Activators | Rubber Chemistry
Model substances have been used to demonstrate other possible routes for the formation of zinc sulfide during vulcanization. The effect of zinc oxide and stearic acid on the rate and degree of crosslinking is associated with participation of these compounds in such reactions.

SULFUR VULCANIZATION OF NATURAL RUBBER FOR BENZOTHIAZOLE
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 mechanisms that have been proposed for the different steps in vulcanization chemistry are critically evaluated with the

Influence of vulcanization temperature on ... - ScienceDirect
Blends of natural rubber and styrene-butadiene rubber were prepared by solution mixing and vulcanized with a system sulfur–accelerator at 433 K and 443 K in order to study the vulcanization kinetic and the influence of the vulcanization temperature on the final structure of the blends.
