What are thermoplastic and thermosetting polymer give examples of each?
Answers
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.Epoxy resin is an example of a thermosetting plastic. A thermosetting plastic is a polymer that irreversibly becomes rigid when heated.
Answer:
A thermoplastic polymers are the linear or slightly branched long chain molecules capable of repeatedly softening on heating and hardening on cooling. These polymers posses intermolecular forces of attraction intermediate between elastomers and fibres. For example polythene, polystyrene, polyvinyls, etc.
A thermosetting polymer are cross linked or heavily branched molecules, which on heating undergo extensive cross linking in moulds and again become infusible. These cannont be reused. For example are bakelite, urea-formaldehyde resin, etc.
