RELATIONSHIP BETWEEN STRUCTURE AND SHAPE MEMORY EFFECT OF SEGMENTED POLYURETHANES
摘要:
The shape memory behavior of a series of PCL/MDI/BDO segmented polyurethanes of different composition is presented. The molecular weight of the PCL diols is in the range of 1600-7000. It is found that the shape memory effect of segmented polyurethanes is really related with the crystallinity of the soft segment regions and the formation of stable hard segment domains as predicted by the model proposed in our previous papers.
