Thermoplastic Polyolefin Elastomer Blends for Multiple and Reversible Shape Memory Polymers

This work reports a novel type of reversible shape memory polymers (RSMPs) from commercially available thermoplastic polyolefin elastomers (POEs). Two RSMPs based on Dow Chemical's POE Engage 8003, Engage 8137, Engage 8180, and olefin block copolymer elastomer Infuse 9007 were prepared by simple blending of the commercial products having different melting temperatures. The multiple and reversible shape memory performances of the as-prepared blends were clearly demonstrated. This work provides a facile and low-cost method for the large-scale preparation of the reversible shape memory materials. It broadens the source of the materials for the design and development of RSMPs.
