These materials were characterized using wide angle X-ray diffraction and differential scanning calorimetry. Polytetramethylene glycol based polyurethane showed soft segment crystallinity while the other two were amorphous. This feature has been connected with the specific nature of the polyols.Polymer ScienceEFFECT OF THE TYPE OF POLYOL ON THE SOFT SEGMENT CRYSTALLINITY IN POLYURETHANE BASED ON METHYLENE BIS(CYCLOHEXYL DIISOCYANATE)
