Question

Explain with examples, branched and linear polymers.

Answer 1

Branched polymers :- These polymers consist of a chain structure having one main chain of molecules with smaller chains as branches of the main chain. They have low density.

Example : Polypropylene with methyl groups as branches, LDPE

Linear polymers :- They are made of long continuous chains without any excess attachments (branches). The repeating units are joined to form a long chain.

Examples : Polyethene, PVC.
