Question

what is the meaning of thermoplastic Polymers and thermosetting polymers ??​

Answer 1

Answer:

 1.)Thermoplastic polymers are those plastics that can be softened on heating, whereas thermosetting plastics are hard even when heated.

 2.)Thermoplastics are soft and stretchable, whereas thermosetting plastics are hard and brittle.

 3.)Thermoplastics are linearly-linked polymers, whereas thermosetting plastics are cross-linked polymers.

 4.)Thermoplastics are also known as thermoplasts, and thermosetting plastics are also known as thermosets.

Answer 2

Answer:

1.Thermoplastic polymers: these are linear or slightly branched long chain molecules capable of softening on heating and hardening on cooling.

Example, Polystyrene and polyethene.

2. Thermosetting polymers : these polymers are cross linked or heavily branched molecules which on heating undergo extensive cross linking in moulds and again become infusible.

Example, Bakelite, urea formaldehyde resin
