Description
A thermoplastic, rubbery polymer. Polyisoprene (cis-1,4-polyisoprene), is the primary component in Caoutchouc that was used to make vulcanized natural rubber. Both the cis and trans forms of the polymer may be produced synthetically. The trans form resembles Gutta-percha. Both types can be vulcanized with Sulfur.
