Question

The plastics in which monomers are arranged in a straight chain are known as thermoplastics

Answer 1

Answer:

Thermoplastic polymers are long-chain polymers in which inter-molecules forces (Van der Waal’s forces) hold the polymer chains together. These polymers when heated are softened (thick fluid like) and hardened when they are allowed to cool down, forming a hard mass. They do not contain any cross bond and can easily be shaped by heating and using moulds. A common example is Polystyrene or PVC (which is used in making pipes).
