Question

Which of the following is the biodegradable polymer of polyamide class?
A. Nylon-6,6
B. Nylon-2-nylon-6
C. Dextran
D. PHBV

Answer 1

Polymer is generally a combination of two words known as poly and mer where poly means many and mer refers with parts i.e. many parts as polymers are made up with repeating units of monomers where monomer is single part of any unit.

Complete answer:
Biodegradable polymers are those polymers which can decompose under aerobic or anaerobic conditions or in an easy manner we can say that which can be broken down with the help of living organisms.
Nylon-2-nylon-6, Dextran and PHBV are said to be biodegradable whereas Nylon-6,6 which is a type of polyamide or nylon is kept in the category of non-biodegradable substances. On the other hand Dextran and PHBV in which dextran is formed by the polymerization of many glucose units and PHBV is biodegradable, non-toxic, biocompatible plastic produced naturally with the help of bacteria.
Nylon-2-nylon-6 is a polyamide formed by the condensation of hydroxybutyric acid or we can say 3-hydroxybutanoic acid. Polyamide can be defined as a polymer with repeating units linked with the help of amide ions.

The biodegradable polymer of polyamide class is Nylon-2-nylon-6, thus we can say that option B is the correct answer.

Note:
Polymers are formed by the process of polymerization. It is the process in which small monomers are joined together through the process of addition polymerization and there are many industrial and other uses of polymers.
