Step-by-step solution
Neoprene (CR), also called polychloroprene or chloroprene rubber, synthetic rubber produced by the polymerization (or linkage together of single molecules into giant, multiple-unit molecules) of chloroprene. Natural rubber is polyisoprene. It is a polymer of hydrocarbon-isoprene. Polyisoprene is an addition polymer. It is cis-1, 4-polyisoprene. Teflon is a brand name for a synthetic chemical called polytetrafluoroethylene (PTFE). Orlon is made from polymerized acrylonitrile.
