ThermoplasticPolymerThese plastics soften when heated and harden when cooled Theprocesses are totally reversible and can be repeated Thesematerials are normally fabricated by the simultaneous applicationof heat and pressure They are linear polymers without anycrosslinking in structure where long molecular chains are bondedto each other by secondary bonds andor by van der waals bondsThey have the property of increasing plasticity with increasingtemperature which breaks the secondary bonds between individualchainsEvery thermoplastic polymer follows stress and strain curve whenit is loaded under any applied loadByclose refering to stress and strain diagram we can understand themechanical behaviour of thermoplastic polymers As we apply load ona polymer the youngs See Answer
