Answer 1

Answer:

Define thermoplastics and thermosetting polymers with two examples of each. Thermoplastic polymers are linear (slightly branched) long chain polymers, which can be repeatedly softened and hardened on heating. ... Examples of thermosetting plastics include bakelite, urea-formaldehyde resins.

Answer 2

Answer:

THERMOPLASTIC:-denoting substances (especially synthetic resins) that become plastic on heating and harden on cooling, and are able to repeat these processes.

THERMOSETTING POLYMER:-Thermosetting polymers are cross-linked or heavily branched polymers which get hardened during the molding process. These plastics cannot be softened again on heating. Examples of thermosetting plastics include bakelite, urea-formaldehyde resins.
