Question

Match the given polymeric structures with its corresponding type of polymer.

• A. Linear polymer
• B. Branched polymer
• C. Cross-linked polymer

Answer 1

Polymers are classified as linear, branched and cross-linked polymers depending on their structure.

• Linear polymers are high density polymers having no branches in it. For example, HDPE (high-density polyethylene).
• Branched polymers are low density polymers having branches in its structure. For example, LDPE (low-density polyethylene).
• Cross-linked polymers have monomer units with branches, linked with each other such that they form a network. They are also called network polymers. For example, bakelite.
