Natural Rubber Vulcanization using Chalcogenide Hybrid Inorganic/Organic Polymers
A new high sulfur content polymer has been developed for tire vulcanization. This polymer may improve chemical compatibility, mixing, and result in more efficient crosslinking. Background: Sulfur, the traditional vulcanizing agent for tire rubber, is largely insoluble in rubber precursors and requires high temperatures to form crosslinks. Even with...

Novel High Refractive Index and Abbie Value Polymers for Advanced Lower Cost Optical Eyewear
Copolymerization of chalcogenide halides with widely available unsaturated monomers is used to create advanced polymer materials for consumer plastic optics, consumer eye wear, and smart phone plastic optics. Background: Sulfenyl chlorides are a widely known but largely ignored class of sulfur compounds that are highly reactive toward nucleophiles...
