Structure Of Monomer Unit Of Natural Rubber Is

Isoprene or 2 methyl 1 3 butadiene is a common organic compound with the formula ch2 c ch3 ch ch2.

Structure of monomer unit of natural rubber is.

The term polymer comes from the greek poly meaning many and mer meaning parts. 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. Isoprene is an unsaturated hydrocarbon. Synthetic rubbers are often based on butadiene which is structurally related to isoprene.

The structure of isoprene is given below. Macro considerations natural rubber is a polymer a long chain like molecule that contains repeating subunits. The monomer of natural rubber is isoprene. C h c h 2.

An addition polymerisation joins thousands of isoprene units together to form poly isoprene or natural rubber. Microstructure refers to the way individual monomer units are distributed along the chain and the geometry in which they are distributed. 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. Its iupac name is 2 methylbut 1 3 diene.

In its pure form it is a colorless volatile liquid. 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. Natural rubber is an elastomer. C c c h 3.

Briefly explain the properties of elastomers. Williams named the compound in 1860 after obtaining it from thermal decomposition of natural rubber. Natural rubber is a linear polymer of isoprene. Isoprene is a natural monomer that polymerizes to form natural rubber most often cis 1 4 polyisoprene but also trans 1 4 polymer.

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. The monomer unit for natural rubber is isoprene.
