vulcanization

Chemical @CT07136@ of high-molar-mass linear or branched polymers to give a @P04742@.
Notes:
  1. The @P04742@ formed often displays rubber-like elasticity. However, a high concentration of crosslinks can lead to rigid materials.
  2. A classic example of vulcanization is the @CT07136@ of cis-polyisoprene through sulfide bridges in the thermal treatment of natural rubber with sulfur or a sulfur-containing compound.
