Design and synthesis of polyuethane membranes with different hard to softsegment ratio

The polyurethane polymer were prepared by solvent polymerization. Structural characteristics of themembranes were studied by X-ray diffraction to confirm the interactions between PU segments. TheXRD analysis of synthesized PUs shows higher peak intensity in PU-۴:۱:۳ due to a higher percentageof hard segments, indicating increased crystallinity.
