Basically, the amorphous polymer that obtains on XRD is due to high-temperature treatment (destructed materials) or the material was already in the non-crystalline phase. To make it easier, just try to find the article based on the polymer materials name.

the main infromation you can get is short rnge order, or radial distribution function

Dear Hitesh Sharma,

Please see the attached presentation.

@ Engin Ciftyurek : I already have this ppt and it gives some basic idea on amorphous xrd. But I am looking for some research papers / articles on the topic.

Thanks anyways.
