the crosslinking efficiency of some vulcanizing agents
The crosslinking efficiency of some vulcanizing agents
The crosslinking efficiencies of several curing agents have been determined from swelling measurements. The results indicate that dicumyl peroxide is a quantitative crosslinking agent for natural rubber, as was previously found to be true of dimethyloctadiene.

Vulcanization is the name originally given to the process Charles Goodyear discovered by mixing sulfur with natural rubber and subjecting it to heat to transform a plastic substance into an elastic substance.
Sulfur vulcanization
Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Even with natural rubber, large amounts of sulfur as well as high temperatures and long heating periods are necessary, with the end products often being of an unsatisfactory quality.
Vulcanization
Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Accelerated vulcanization is carried out using various compounds that modify the kinetics of crosslinking, [3] this mixture is often referred to as a cure package.

Organic Peroxides as Crosslinking Agents | Request PDF
Organic peroxides (PO) are used as crosslinking (vulcanizing) agents. Free radicals generated from PO can abstract hydrogens from saturated rubbers such as polyethylene, ethylene-propylene-diene
De-vulcanization of Tire Rubber | ILLYRIA
Vulcanizing agents are substances that bring about the actual crosslinking process. Other properties, such as tensile strength, gas permeability, low temperature, flexibility and electrical resistance change with the degree of vulcanization. Each cross-linking releases a quantum of energy, making it an exothermal reaction.
