Structure Of Monomer Unit Of Natural Rubber Is

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.

Structure of monomer unit of natural rubber is.

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. Microstructure refers to the way individual monomer units are distributed along the chain and the geometry in which they are distributed. 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. C h c h 2.

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. The structure of isoprene is given below. Isoprene is an unsaturated hydrocarbon. It is produced by many plants and animals and its polymers are the main component of natural rubber.

The monomer of natural rubber is isoprene. He correctly deduced the empirical formula c5h8. C c c h 3. In its pure form it is a colorless volatile liquid.

Briefly explain the properties of elastomers. 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. An addition polymerisation joins thousands of isoprene units together to form poly isoprene or natural rubber. Synthetic rubbers are often based on butadiene which is structurally related to isoprene.

The term polymer comes from the greek poly meaning many and mer meaning parts. Macro considerations natural rubber is a polymer a long chain like molecule that contains repeating subunits. Its iupac name is 2 methylbut 1 3 diene. Isoprene or 2 methyl 1 3 butadiene is a common organic compound with the formula ch2 c ch3 ch ch2.

Isoprene is a natural monomer that polymerizes to form natural rubber most often cis 1 4 polyisoprene but also trans 1 4 polymer. Natural rubber is an elastomer. The monomer unit for natural rubber is isoprene.
