What would the expected DSC profile for a theoretical 100% crystalline polymer, a semi-crystalline polymer and an amorphous look like?
For crystalline polymer and semi crystalline polymer , melting point peak becomes sharp . For semi crystalline materials , polymorphism or allotropism can also be observed .
On the other hand , DSC of amorphous materials show broad melting peak and something called glass transition temperature can be seen for amorphous materials . By these means , we can differentiate between them.
The graphs are given in the attachment.
