Natural rubber is polyisoprene in which monomer units are of isoprene i,e 2-methyl-1,3 butadiene. Natural rubber is obtained in the form of solid particles suspended in a milky white liquid (called latex) that drips from the bark of certain tropical and subtropical trees. Neoprene is a synthetic rubber. The monomer of Neoprene is 2-chloro-1,3-butadiene, it is commonly known as chloroprene.
