Used of Natural Rubber in Polymerization…
Used of Natural Rubber in Polymerization(i) Sulphur forms crosslinks at the reactive sites of the double bond and thus rubber gets stiffened.
(ii) The stiffness of rubber depends upon the amount of sulphur added, e.g. when 5% sulphur is used as a cross-linking agent
(iii) The obtained vulcanised rubber is used for manufacturing tires
(iv) If 30% sulphur is used to obtain vulcanised rubber (ebonite) is used in making battery case.
