Polyisoprene is strictly speaking a collective name for polymers that are produced by polymerization of isoprene. In practice polyisoprene is commonly used to refer to synthetic cis-1,4-polyisoprene, made by the industrial polymerisation of isoprene. Natural forms of polyisoprene are also used in substantial quantities, the most important being 'natural rubber' (mostly cis-1,4-polyisoprene), which … garlic extraction procedureWebFeb 25, 2024 · Explanation: 1).
