Example of linear polymer is ______________?
Correct answer: D. both A and C
- A. High density polythene
- B. Low density polythene
- C. PVC
- D. both A and C
Explanation
High-density polythene has relatively unbranched, linear chains, and PVC is also generally classified as a linear addition polymer. Low-density polythene is highly branched, so it is not the linear example here. Therefore both A and C are correct, making option d the best choice; a student may select only HDPE by overlooking the linear structure of PVC.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
