Question

what are linear and branched polymers​

Answer 1

Answer:

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.

Answer 2

polymer is a general term for any molecule that is a long string of smaller repeating parts formed by carbon-carbon bonds. The bonds can form long straight chains known as linear polymers, or parts can branch off from the chain, forming branched polymers. The polymers can also be cross-linked.
