Description
A thermoplastic, rubbery polymer. Polyisoprene (cis-1,4-polyisoprene), is the primary component in 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.
Synonyms and Related Terms
polyisoprène (Fr.); poliisopreno (Esp.); polisoprene (It.); poliisopreno (Port.); cis-1,4-polyisoprene; trans-1,4-polyisoprene;
Other Properties
Soluble in aliphatic and aromatic solvents. Insoluble in acetone, diethyl ether. Burns with a dark yellow, sooty flame that smells like burnt rubber.
