Question

Among the following polymers, which polymer is an addition polymer?
A. Polypropylene
B. Dacron
C. Nylon 6, 10
D. Bakelite

Answer 1

Hint: Addition polymerization is going to be carried out by an initiator and in addition reactions no side products are going to form after the completion of the reaction. Only polymerized products are going to form as the major product.

Complete step by step answer:
- Addition reactions generally happen in between unsaturated monomers.
- Unsaturated alkenes generally undergo addition polymerization.
- Coming to the given options, Option B, Dacron. The monomeric units of Dacron are ethylene glycol and terephthalic acid. The monomers contain different functional groups in their structures and they undergo condensation polymerization to form Dacron as the product.
- Coming to option C, Nylon 6, 10. The monomeric units of Nylon 6, 10 are decanedioyl dichloride, and hexamethylenediamine. The monomers contain different functional groups in their structures and they undergo condensation polymerization to form Nylon 6, 10 as the product.
- Coming to option D, Bakelite. The monomeric units of Bakelite are phenol and formaldehyde. The monomers contain different functional groups in their structures and they undergo condensation polymerization to form Bakelite as the product.
- Coming to option A, Polypropylene. The monomeric units of Polypropylene are propylene. The monomer unit propylene contains a double bond (unsaturation) in its structure. The preparation of the polypropylene as follows.
- Therefore Polypropylene is going to form through addition polymerization reactions.
So, the correct answer is “Option A”.

Note: In condensation polymerization reactions by products like water and methanol are going to be released along with the main products. But in case of addition polymerization reactions the scenario is different no by products are going to form.
