Question

Among the following, the linear chain polymer is/are

• A. Low density polythene
• B. Polyvinyl chloride
• C. High density polythene
• D. Bakelite

Answer 1

Answer: (B), (C)

High density polythene

Low-density polythene is a branched-chain polymer made from the monomer ethylene.
Branched-chain polymer consisting of linear chains having some branches.

High density polythene and polyvinyl chloride (PVC) are linear polymers.

Bakelite is a cross linked polymer. They are formed from
bi-functional and trifunctional monomers. They Contain strong covalent bonds between various linear chain.

Hence, option (a) and (d) are correct.
