Challenges of Shape Memory Polymers : A Review of the Progress Toward Overcoming SMP's Limitations
TL;DR: In this paper, a review of the literature on shape memory polymers (SMPs) is presented, and it is concluded that covalently crosslinked glassy thermosets appear to be better SMP candidates because of their intrinsically higher modulus, greater thermal and chemical stability, higher shape fixity and recovery, and possibly their longer cycle life.

Polyurethanes having shape memory effects
TL;DR: In this paper, the effects of soft segment molecular weight (Mn = 2000, 4000 and 8000), soft segment content (50-90%), and maximum strain (em = 100, 200, and 600%) on the cyclic tensile properties as well as the dynamic mechanical, and mechanical properties below (25°C) and above (65°C), were studied.
