Shape memory polymer properties
WebbThe properties of SMPUs can be improved significantly by improving the phase separation and the stability of the hard segment. This chapter introduces three strategies to improve the properties of SMPUs. The first is achieved by employing 4,4′-methylene-bis(2-chloroaniline) (MOCA) as the chain extender to form a stable hard segment phase.
