Structure Of Monomer Unit Of Natural Rubber Is

Briefly explain the properties of elastomers.

Structure of monomer unit of natural rubber is.

The monomer unit for natural rubber is isoprene. 2 buna n nitrile rubber it is obtained by polymerization of 1 3 butadiene acrylonitrile in the presence of a peroxide catalyst it is used. The structure of isoprene is given below. 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. Williams named the compound in 1860 after obtaining it from thermal decomposition of natural rubber. Synthetic rubbers are often based on butadiene which is structurally related to isoprene. C c c h 3.

Isoprene is a natural monomer that polymerizes to form natural rubber most often cis 1 4 polyisoprene but also trans 1 4 polymer. Isoprene or 2 methyl 1 3 butadiene is a common organic compound with the formula ch2 c ch3 ch ch2. An addition polymerisation joins thousands of isoprene units together to form poly isoprene or natural rubber. Isoprene is an unsaturated hydrocarbon.

Its iupac name is 2 methylbut 1 3 diene. The term polymer comes from the greek poly meaning many and mer meaning parts. In its pure form it is a colorless volatile liquid. 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.

C h c h 2. 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. 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. Natural rubber is an elastomer.

The monomer of natural rubber is isoprene. Microstructure refers to the way individual monomer units are distributed along the chain and the geometry in which they are distributed. Natural rubber is a linear polymer of isoprene.
