प्रश्न
What is the role of sulphur in the vulcanisation of rubber?
Advertisements
उत्तर १
Rubber is made of hydrocarbon chains, basically carbon and hydrogen. These chains slide over one another and get tied to one another which leads to natural rubber being sticky. When sulphur is used in the vulcanisation process, it reacts with these chains and forms disulphide (or similar) bonds. Sulphur forms cross linkages at the reactive sites of the double bonds because of which rubber gets stiffened.
उत्तर २
In vulcanization, sulphur forms cross-link at the reactive sites of double bonds of natural rubber so the rubber gets stiffened.
