A series of four samples of segmented PUUSs, with different hard to soft segment ratio, was prepared and characterized. The structure and composition of the PUUSs was confirmed by NMR spectroscopy. DSC analysis and AFM measurements revealed that the copolymers show a high degree of phase separation between hard and soft segments. TG analysis in nit rogen showed that PUUS copolymers were stable up to 200°C.
