Natural rubber is a polymer derived from?
|
|
isoprene
|
|
|
ethylene
|
|
|
propylene
|
|
|
butadiene
|
Explanation:
Detailed explanation-1: -Natural rubber or raw rubber consists of basic material latex which is a dispersion of isoprene. During the treatment, this isoprene forms a high molecular weight polymer of isoprene. Natural rubber can be obtained from five hundred different species of plants.
Detailed explanation-2: -Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree. Natural rubber is from the monomer isoprene (2-methyl-1, 3-butadiene), which is a conjugated diene hydrocarbon as mentioned above.
Detailed explanation-3: -It is made by the polymerization of isoprene (2 methyl-1, 3-butadiene) which has a chemical formula (C5H8) n and it is known as cis-1, 4-polyisoprene.
