Structure of monomer unit of natural rubber is.

The monomer of natural rubber is isoprene. The structure of isoprene is given below. Its iupac name is 2 methylbut 1 3 diene. Williams named the compound in 1860 after obtaining it from thermal decomposition of natural rubber.

Isoprene or 2 methyl 1 3 butadiene is a common organic compound with the formula ch2 c ch3 ch ch2. Polyisoprene a polymer of isoprene c5h8 that is the primary chemical constituent of natural rubber of the naturally occurring resins balata and gutta percha and of the synthetic equivalents of these materials. The monomer unit for natural rubber is isoprene. C c c h 3.

Natural rubber is an elastomer. An addition polymerisation joins thousands of isoprene units together to form poly isoprene or natural rubber. Depending on its molecular structure polyisoprene can be a resilient elastic polymer elastomer as in the case of natural rubber and isoprene rubber or a tough leathery resin as in the case of natural and. Isoprene is an unsaturated hydrocarbon.

Isoprene is a natural monomer that polymerizes to form natural rubber most often cis 1 4 polyisoprene but also trans 1 4 polymer. Polyisoprene polymer of isoprene c 5 h 8 that is the primary chemical constituent of natural rubber of the naturally occurring resins balata and gutta percha and of the synthetic equivalents of these materials. He correctly deduced the empirical formula c5h8. The term polymer comes from the greek poly meaning many and mer meaning parts.

Briefly explain the properties of elastomers. Synthetic rubbers are often based on butadiene which is structurally related to isoprene. In its pure form it is a colorless volatile liquid. Natural rubber is a linear polymer of isoprene.

Depending on its molecular structure polyisoprene can be a resilient elastic polymer as in the case of natural rubber and isoprene rubber or a tough leathery resin as in. It is produced by many plants and animals and its polymers are the main component of natural rubber. 1 buna s styrene butadiene rubber it is obtained by the polymerization of buta 1 3 diene styrene in the ratio of 3 1 in the presence of sodium it is used for making automobile tyres footwear.
