Question
What are linear polymer and branched chain polymers? How do these differ from own linked polymers?
Solution
Linear polymers are well packed and have high densities, high tensile strength and also have a high melting point, e.g., high-density polyethene.
Branched chain polymers are irregularly packed and have lower tensile strength and lower melting point than linear polymers, e.g., low-density polythene. These are different from cross-linked
polymers in the sense that the cross-linked polymers are hard, rigid and brittle e.g., bakelite.
