The synthesized PCU was then characterized by infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, small-angle X-ray scattering, and tensile strength measurement. The IR showed that the polymer synthesized by the above two methods both have the polycarbonate-urethane structure and the tensile measurement showed good mechanical performance of the polymer. The DSC and TGA data showed that there is an obvious soft-hard glass transition area, which indicated the existence of the micro-phase separation structure. The extent of the phase separation was affected by the ratio of starting materials, the molecular weight of PCD, and the polymerization method. The decomposition upon heating was observed in two steps. SAXS result showed that the radius (r_2), the distance between domains (d_2), and gyral radius (R_2) of hard segment micro-domain were fairly affected by the starting materials ratio and soft segment content.

IR结果表明两种方法合成的聚合产物均具有聚碳酸酯聚氨酯的结构；拉伸实验表明聚合产物具有良好的力学性能；DSC、TG结果表明，聚合物呈现出较为明显的软硬段玻璃化转变区，表明存在微相分离的结构，相分离的程度受原料配比、软段分子量、聚合方法的影响，其热分解分为明显的两个阶段； SAXS结果表明，聚合物原料配比、软段含量的变化对硬段微区回旋半径R_2，微区间距d_2，微区半径r_2影响不大其值分别为9.5(A|°、29、7.4，但对软段的微区半径及间距影响较大，随着软段含量的增大，软段微区的半径r1和间距d1都增大。
