Sulfur vulcanization been uncertainly as to whether it proceeds in a radical or ionic manner. The reactive sites, often referred to as 'cure sites', are unsaturated groups such as alkenes and allyls. During vulcanization, sulfur bridges are formed between these sites, crosslinking the polymer. These bridges may consist one or several sulfur atoms. Both the extent of crosslinking and the number of sulfur atoms in the crosslinks strongly influences the physical properties of the rubber produced: 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
Texas Gulf Sulfur Company Texas Gulf Sulfur Company The Texas Gulf Sulphur Company was one of the largest sulfur mining companies in the world from 1919 to 1981. The Gulf Sulphur Company was formed on December 23, 1909 by a group of investors from St. Louis and Texas. The company was formed to exploit the newly discovered sulfur deposit in the Big Hill salt dome near Matagorda, Texas, using the Frasch Process. In 1916 Bernard Baruch and J.P. Morgan took control of the company and Seeley W. Mudd became President. On 16 July 1918, the company was renamed the Texas Gulf Sulphur Company. Construction
