In this study, novel multiple shape memory polymers (MSMPs) are successfully prepared using the facile, inexpensive, and effective approach of multistage polymerization procedures. The resultant samples comprising three copolymers with well-separated glass transition temperatures can change their shapes in a pre-defined way over a broad temperature range with almost full recovery of all temporary shapes. We anticipate that a similar approach can be broadly applicable to other stimuli-responsive materials for the design and fabrication of diverse triple- or multiple-SMPs.
