Some polyurethane elastomers with different macromolecular structure were synthesized and their dynamic mechanical properties were determined. It is found that the compatibility between the soft segment and hard segment phases of the polyurethane is mainly depended on the macromolecular chain structure. The existence of graft chains has a great effect on the morphology and damping property of the polyurethane elastomers.
- polyurethane elastomer,
- compatibility,
- damping property
