Rubber vulcanization agents of sulfur olefin adduct - The
Superior vulcanization agents for rubber are prepared by reacting sulfur with at least one olefin at 120°-200° C. in an aqueous reaction media with agitation. In one embodiment, the vulcanization agent comprises a sulfur/olefin adduct having from about 39% to about 46% by weight of free elemental sulfur level.

Sulfur vulcanization
Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of a variety of hardness, elasticity, and mechanical durability by heating them with sulfur or other equivalent curatives or accelerators. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties.

Sulfur/Olefin Copolymers as Vulcanizing Agents for Rubber
Sulfur/olefin copolymers are known as vulcanizing agents for rubber, but synthetic procedures for these materials are poor and there is little in the literature to relate the structure of the copolymer with the vulcanizate properties of the rubber.

The science behind vulcanization. Vulcanizing agent is a material, usually sulfur, that is used in the chemical process of vulcanization. Vulcanization Agent (Rubber makers sulfur) gives natural rubber or other polymers more strength, elasticity and durability by the addition of sulfur or other accelerators such as zinc oxide and peroxide.

The reaction of sulfur and sulfur compounds with olefinic
Zinc oxide alone produces little change in the composition of the complex product mixture, but in the presence of stearic acid, and more so when the thiazole is also present, significant changes are produced in the distribution of combined sulfur which reflect more efficient use of the sulfur in crosslinking reactions, and which can be related rationally to important effects exerted by these additives on the sulfur‐vulcanization of natural rubber.

Vulcanization
Vulcanization with sulfur. By far the most common vulcanizing methods depend on sulfur. Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. The cure package consists of insoluble sulfur together with a compound that modify the kinetics of crosslinking.
