Explain with example, branched and linear polymers.

Explanation

Linear polymers : The polymers made up of long continuous chain without any branches are called linear polymers. They have high melting points, high densities and high tensile strength. Example : Polyethene, PVC.
Branched chain polymers : The polymers made up of main chain (linear chain) with smaller chains as branches of main chain are called branched chain polymers. They have lower melting points, densities and tensile strength as compared to linear polymers.
Example : Polypropylene.
