Paper Abstract

In this paper, a series of shape memory polyurethanes (SMPUs) containing polycaprolactone diol (PCL4000), 1,4-butanediol (BDO), and 4,4'-diphenylmethane diisocyanate (MDI) were synthesized using bulk polymerization. Their thermal properties, thermomechanical properties were analyzed by differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA), and the shape memory effect was also investigated. Moreover, one kind of shape memory polyurethane fiber was spinned by melting method from these prepared SMPUs and its shape memory properties were also investigated. The results showed that synthesis of shape memory polyurethane using bulk polymerization can effectively enhance the properties of polyurethanes, save cost and improve efficiency compared with solution polymerization.
