Question

saran is crystalline but pvc is amorphous why????

Answer 1

Amorphous materials are more sensitive to stress failure due to the presence of hydrocarbons. ABS and PVC are commonamorphous thermoplastics. Semi-crystalline polymers have a highly ordered molecular structure. These do not soften as the temperature rises, but rather have a defined and narrow melting point. thank you friend if you like my answer please mark it as bring you good luck and have any doubts ask me in the comment box
