Explain with examples, branched and linear polymers.
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.
